MAVLink 3DR Radio on an APM 2.5 Multicopter Board - Overview, Setup and Troubleshooting

3DR radio installation and use
I finally got this radio MAVLink all working this morning after wrestling with it for the last three days; I wanted to show how to set it up and shoe the problems that I had and how I overcame them.
I cover the following in the video --
What comes in the pack?
Two radios
Antennas
Connecting cable (will not work with the dedicated port on the APM 2.5)
Connecting to the APM -- UART0/3DR dedicated port -
Cable for the wrong connection -- what you need to buy -- connectors for dedicated ports -- DF13 5 position and DF13 4 position connectors/cables
What you need to do to connect it -
Ground station
After XP -- no need to install driver
Air station
Make a suitable cable remembering to cross the TX and RX cables
How to set-up -
• Plug into PC
• Power up model
• Solid green light shows an active link (red LED shows activity)
• Start Mission Planner
• Go to Initial Setup -- 3DR Radio -- Load Settings
• If you can see both radios on this screen the ground station and air side radio are working
To use -
Select COM port and click connect!
Gotchas -
• 57k baud
• If you can't see the APM over the link
• Check the cable from APM to Radio -- swap TX/Rx pins
• Update firmware in both radios
• Ground station use connector supplied
• Air side use the FTDI connector and the special cable

[@glennwardle4250]

i followed you video used the ftdi adapter wired as you said .. it worked a treat .. worked straightaway , i wish id found your vid earlier ..thanks a lot glenn

[@jeffdyck131]

Absolutely love your videos. Well prepared and presented and very informative. I have watched most of them in conjunction with setting up various boards and options. Today, I'm setting up the 3DR telemetry on a 2.7 HK APM board and it worked flawlessly thanks in part to your great video. Hope more people utilize these useful tools I I have. Thanks again and keep it coming.

[@Painless360]

Hi Jeff, thanks for the comment, it's always great to hear that I've helped another hobbyist. Happy flying!

[@chrisleech1565]

I was under the impression that the Air side was done thru the Mission Planner. Or at least I have seen or read it happens that way. Of course I updated the FW on the Ground with the FTDI just fine. So I am encouraged to here of your experience. Just figured out how to do the MinimOSD and the CPPM FW on my FrSKy D8RIIPlus with the FTDI. All ready paid for itself. Thanks for this.

[@Painless360]

Thanks for the comment, I also read the same things on the web when I was trying to set this up and that's exactly why I made the video when I'd figured it out and got it working. Thanks again, happy flying!

[@chrisleech1565]

Painless360 Feeling is mutual of course sir. Now what if I really got stuck with ER9X and the flight modes/switches for APM 2.5 Painless? Would you be able to offer any advice? Throw in your two pence :-) Just hit a wall with the version / build of the FW . Brand new to RC and the 9X. Need to get some water under the bridge (Get away from the workbench and fly) with this 650mm quad trainer.

[@funkygrib1]

Painless360 is always good referance material ! Your a scholar and a gentleman. The background info was great and the solution was quick and easy Didn't work first time in the plane Tx, Rx crossed :-) The video gave me confidance what the problem was, second boot, Mavlink was perfect Again thank you

[@Painless360]

Wonderful! Glad you got it all working. Happy flying!

[@Rangler6475]

your video helped me so so much. THANK YOU! I had my receiving and transmitting cables in the wrong slot so I popped them out and switched them. It connected right up after that.

[@Painless360]

Glad it's all working - happy flying! :D

[@Painless360]

Hi Alan, I've not read about the timeout it on the blogs (and can't see it in the code) but from the experience setting up these radios this seems to be the case - you can see it happen in the video. The only other thing I did when trouble shooting was check that there were no shorts between any of the pins on both the airside radio and the APM socket using a multimeter. I've read that some boards had excess solder that caused problems. Good luck locating the problem on yours.

[@Salomon1502]

I can always find useful info on your channel. Thank you for all your assistance. !!!

[@artpam]

Thank you very much for this tutorial. Just now setting up my APM 2.6, had everything working so decided to tackle the 3DR radios. I had these working before with multiwii, but even though I had solid green lights indicating they were linked, I had no telemetry. Luckily I still had my FTDI adapter from my old MWii/Arduino days! I flashed them both, then ran the setup in Mission Planner, and they are talking now! 8^)

[@Painless360]

Great news, glad the video helped! :)

[@MrSupermariocanada]

I could not get the two to connect with each other even following all the steps until I saw that even reset to default the number of channel goes to 50 and when I changed that to 10 on both it finally saw each other. Still trying to get working with APM but I think I got bad cable waiting for a replacement. Hope it will be OK. By the way great video series, keep up the good work!!

[@matthetriker]

forgot to say got the ftdi adapter made the leads up but have'nt a clue what to do next ps thanks for all your great videos

[@Painless360]

+mat green Click on 'Upload firmware Local' Button at the top of the screen (5:51) you'll need to update both and make sure they are set identically. Best of luck.

[@NeilHodgsonDARKHOURS]

Hello I have everything working great the only thing is when i go into terminal and try connect in terminal all I am getting is streams of unknown writing Dose terminal only work using usb cable only ? Thank You

[@drz4000]

Best APM videos ever!

[@Painless360]

Thank you for the feedback and supporting the 'spirit of the channel'. Happy flying!

[@Painless360]

Hi Busu, that's right. 915Mhz for the US and 433Mhz for Europe and other countries that don't allow 915Mhz. Happy flying!

[@plugtheheliflyer]

Hi Painless I don't know if a dud or a setting issue ,I was having lots of trouble with the PID settings,No matter what i did i could not get a steady flight when adding I /D As soon as i added any of the two the quad's motors would slow down like a oscillation . So what your saying then is the bluetooth of the crius might not work with APM 2.6. The crius board GPS and module and OLED is up for offers.

[@seanzacharyuy7647]

So my situation is, I've got solid lights, apm knows it's connected, but I can't do anything on apm, as in its not letting me see what's happening to the quad in real time. Any ideas on how to fix this?

[@MustangO3]

Thanks painless. I fix the rolling over problem. It was just balance. I just was wondering if you know way to check if the telemetry radio is smoke or not. It's still lights up but doesn't seem to be talking. I will go through the videos again. Thank you

[@Painless360]

If you can connect to it - it's ok. If you can't then you've probably cooked it ;) Best of luck!

[@Mr17luchin]

Hello, I managed to solve the issue of the telemetry 433 version but now I have the same problem that mission planner does not get data, now if I connect the USB cable to the PC it works and when disconnecting the cable without disconnecting the battery and connect the telemetry works but does not send data but I see them in mission planner but I can not do anything just watch them. the green lights are fixed and the red ones blinking (connect and send me message getting params)

[@michaelguest9428]

Great video! What if I plugged the Sik Radio into the telem 1 port and I do not get any light on it? I have a Pixhawk 1. The other one is plugged into computer and I get a blinking blue light.

[@Painless360]

If there is no light then that may be no power - what troubleshooting have you already done?

[@lowrevsrc]

yes I did think that myself. thanks for all your help again

[@Painless360]

Hi Alan, not tried that exact board but this doesn't seem to be board specific from the posts I've found in the forums. I struggled with mine until I rewired the cable to the APM board from scratch to make sure I'd crossed the Tx and Rx lines and then flashed both units with the latest firmware using the Mission Planner as shown in this video. The wireless connection has to be made within a minute after power on at the air side else it all times out. Hope this helps.

[@goofapilot8662]

Hi Painless, Wonder if you can shed some light, I have a Bixiler 2 with Hextronic APM board and Telemetery Radio's and every thing is working fine, I have built a Zeter Phantom and fitted a Mini Hextronik APM board and installed the 2 radio's from the Bixiler 2, the board works fine, the 2 Radio's see each other, but I cannot connect the Mission planner to the Radio's, I have spent hours trying to solve this to no avail, what am I missing, Regards Goofa.

[@Painless360]

Hi Goofa. I also struggled with the APM radios. In the end I did get them working, you can see more at 3DR Radio on an APM 2.5 Multicopter Board - Overview, Setup and Troubleshooting My radios stopped trying to connect after a few mins following power on so make sure you don't hang about. Happy flying!

[@lowrevsrc]

hi painless. I can get my 3dr to connect and it shows my radio state and if I move my quad the compass horizon moves BUT and I bet you knew there was one ? I can't get my data to download when I hit the load settings tab. any help please. thanks

[@Painless360]

I'd suspect that it's firmware related issue. You could update both radios but I'd be tempted, if they are working, to leave it alone and fly ;)

[@MustangO3]

Thanks for your videos. You just got me through my first build, a 300mm hex with APM. I have a question if you have time. I had a roll over on testing and when I powered back up I saw smoke. Unplugged and found out the 3dr antenna mount had cracked. I soldered it back and powered up. It lights up and flashes for about a minute then the light goes solid but it doesn't connect. Any ideas? Also I spliced the OSD into the telemetry cable and it works but had to switch the TX and RX cable for the 3dr to work. Then the OSD data is all over the screen like its trying to fit on a larger screen. Any ideas on that? Thanks again and great job on the videos. John

[@Painless360]

+MustangO3 so you have three things to fix? Flipping on takeoff, damaged telemetry radio and OSD size? We have a video on things to check if you flip on takeoff. Replace any components that have smoked, and I've not seen that on an OSD, check settings.. best of luck!

[@JARC99_]

So this only allows for information to come down from the drone to the pc or could we also send information from the pc to the drone using these 3DR radios?

[@Painless360]

It's two way

[@matthetriker]

ok but how do you actually upgrade firmware / downloads etc ? cheers Mat

[@tptwk]

Do you know where I can buy the DF13 5 position and DF13 4 position connectors/cables? I have the same problem. My cable has a 6 pin connector on one end.

[@Painless360]

eBay has lots. Search for something like 'df13 5 pole' to find them.. Best of luck.

[@itsrron]

Hi Painless, I have, what seems to be the exact same radio telemetry as you do but it seems like my transmitter is not being picked up by the receiver as the green light is just blinking in search for a connection any ideas?

[@itsrron]

I tried everything apart from the ftdi connector as i dont have one but do you think thats what stops them form talking to eachother?

[@Painless360]

rr You need to get yourself an FTDI connector so you can plug the airside radio into the missionplanner software and look at the radio as a 'local' device and flash the firmware/check all the setting on the radio match the groundside one.

[@itsrron]

Painless360 Yeah thats the last thing left, im gonna have to order one tomorrow. thanx for the reply and keep up the great work. Your videos have helped me ALOT

[@plugtheheliflyer]

Hi Painless I have now give up on the crius se 2.5.was having lot's of trouble with settings i got a dud ,so now getting APM 2.6 can i use the bluetooth from the crius .?

[@Painless360]

Hi Plug. Sounds like you may have. I've not tried the BT module with the APM, it's designed to use a radio link (433 in the UK). You can see how to set that up in one of my other videos. I hope you have better luck. What are you going to do with the broken board?

[@TerminalTwo]

Hello, I tried changing the NET ID with this tutorial right here.ardupilot.org/copter/docs/common-configuring-a-telemetry-radio-using-mission-planner.html Followed each and every step carefully. But after I save settings and reboot only the net Id of the Ground Module is changed. The air module's net id remains unchanged and it doesnt pair after the reboot. Also when I open the Sik radio settings page in mission planner and click on load settings, the remote module doesnt load its firmware name. I need to use 2 telemetry modules in parallel. I am experimenting with RTK GPS along with APM. So i need one for the usual telemetry and one for sending the GPS data for RTK.

[@oebele1517]

Thx for your helpful video. The problem only is that I lost the air unit. Do you or somebody else know where I can buy it separately for a reasonable price?

[@Painless360]

EBay? I've got them from lots of places..

[@oebele1517]

Painless360 just to clarify I’m only searching for the air module.

[@Painless360]

I've never seen them sold in anything but pairs..

[@minhdang6502]

Hi, I have a clone 3dr radio from dx.com. The ground module seems to be ok, but the air module's light doesn't come up even I've powered on the APM 2.6 using battery. So is this the hardware problem or the software? Thank you so much

[@Painless360]

Two radio normally has two lights, one for power and the other to show the link is made to the other radio. I had to flash mine as shown in the video to get the settings the same to make it work. I would contact the sender for help. Best of luck!

[@wongbu7043]

Good day, on apm how can i use 2 telemetry modules? First is radiolink prm-03 to get telemetry data on my at10ii and 2nd is a wifi telemetry module so i can connect my phone and use the TOWER app for mission planning. Is there any other port on apm 2.8 that i can use aside from i2c port because i have a compass on it. Thanks.

[@Painless360]

The APM is designed for one device only...

[@wongbu7043]

oh ok. Thanks.

[@letsgocamping88]

Nice helpful video, have you used minimosd at all? I'm having issues with mine only displaying the message 'No MAV data' any thoughts?

[@Painless360]

I've looked at the MiminOSD myself and never been tempted. I suggest tracing the rx and tx lines from the main board and swapping them over to see if that helps. Apart from that I don't have experience to help figure it out. Sorry.

[@Painless360]

Benjamin Harvey Hi Ben, I've just setup a MinimOSD on one of my Multiwii models - you will need to update the code to 2.3 to work. I'm uploading a video as I type that should help. Watch for it on the channel..Happy flying!

[@chrisleech1565]

What exactly did you reconnect to get the heart beat happening just then at 6.58 when you said,"...just reconnecting this"....I am getting some confusing things going on, because I know that I have the thing wired up correctly, I had to solder direct to the UART2 solder pads on the back of the board after I had a failure of the 5 pin DF13 connector shortly after I made the "Wyed" leads to accomodate both the Telemetry And MinimOSD . Either the Tx or the Rx lead connection at the Air radio is faulty, So that is how I got around to my first mod of the APM,The thing of it is I am still not getting APM's Heart Beat. Can you offer any advise? Is there a timing issue for connecting the APM or the Telemetry Radio as I suspect? I am about to order a complete unit. BTW as a return favour, I thought I would inform you of this truly magnificent deal from UAV Objects, an arm of RCTimer >>> www.uavobjects.com/product/arduflyer-2-5-and-avdomecn06plus-with-915-mhz-mavlin/

[@Painless360]

I saw an odd problem where if the connection to the airside radio didn't happen within a very short time after power on at the model end I seemed to lose the option to connect. At the point you mention I unplug the battery from the model and reconnect it (the beeps you here on the video are the ESCs powering up). It always seemed to help clear any problem I had connecting to the radio. Hope this helps. Happy flying!

[@chrisleech1565]

Thanks, I am counting on it. How in the world would you have thought of that in the first place? But I will say that it certainly puts an interesting spin on other interfacing that we negotiate frequently. I had an issue with an arcing caused by making a non deliberate connection of the XT60 with the power dist. board. I am putting a switch on the output of my 3A/5v UBEC so I can have arc free power-up of my APM2.5.2 and peripherals. Regards C

[@chrisleech1565]

Well I'll be, it worked a charm! Thanks pal. I had a feeling about this method and sure enough.

[@Painless360]

Great news - glad it worked for you too. I'm playing with the Mission Planner now, you planning on posting any videos?

[@chrisleech1565]

How did you know? Problem with getting the flight modes configured.

[@minesolo95]

Does this Telemetry Set work with the Mini APM v3.1. I am having some doubts about the wiring.

[@Painless360]

Miguel, search on the channel and use my playlists. You'll find all sorts of helpful pieces. kzbin.info/www/bejne/Zp2sf6dqndtoqsk

[@minesolo95]

Painless360 Thanks a lot. If it weren't for your videos I had given this hobby up a long time ago. Keep up the awesome work

[@Mariz650]

Thank you for your videos, they help alot. I i'm powering my FC with USB cable and trying to mak the connection with MS and telemetry. They load the data in config but then it wont connect. Do the power must come from the battery instead of the USB?

[@Painless360]

+Andre Ferreira I've never tried it like that. I would check that the radio is powered by the USB cable powering the connector. Best of luck!

[@Mariz650]

+Painless360 it is and loads the data in initial setup but it wont connect

[@Painless360]

+Andre Ferreira we ended up flashing one of our sets to get them to work. All we did is in the video. Best of luck!

[@Mariz650]

It works when connected to the battery :D

[@chris_mk5supra]

hi, thanks a lot for your tutorial, theyre are very helpful ! i finaly get my 3rd radio connected but it's VERY VERY slow, baud rate seems ok, 57600, i need about 5 min to have all the parameters on my computer ... any idea how to make this faster ?

[@Painless360]

+christophe levaux Not sure, I'd check all of the setting and make sure that non of the pieces are still set to 9600.. Best of luck!

[@chris_mk5supra]

+Painless360 well i unpluged everything and plug back on and now it s working it was thé power modual le thé apm that causes that it seems thanks

[@MrHandsomejackuk]

i need to get 433 mhz to improve my range i was looking to use a 433 hc12 module, on the quad, and some sort of otg device for my phone.. do you know of anyway to do this with ezgui and usb otg.. as it would be so much easier that bluetooth gorund station bridge.. what device do i need for the groundstation end ?

[@Painless360]

The one I've used is the HobbyKing radio set. The ground station radio has BT on it you can connect to. See it in the Quanum Nova series. It made it very easy..

[@bobf3598]

Wheres the 3DR settings gone??. Not in the latest version of MP. Just Sik Radio and when you try to load settings, all i get is "Failed To Enter command mode" prompt. Must have purchased some clone. Just wish ardupilot update their web pages. Most of the pictures on there are from years ago. Not easy to follow.

[@MrNeil351]

My ground unit is running 1.9 firmware and the air has 1.6 and I cant get them to connect. Would that be the reason? It keeps saying no heartbeat.

[@Painless360]

Try to connect to the air-side radio very quickly after you power on the craft. I've found that leaving it too long can cause the air side radio to 'go to sleep' and lose the ability to connect. Hope this helps. Happy flying!

[@alessandrogiannoni7420]

Hi Painless. I've got the 2 telemetry modules but I have not been able to make them work yet. After power On the radio module both green leds module are solid green, so the connection is established. Red led on air module blink. But I can not Load Settings on the ground module. I don't know why. Only strange thing I can see is that when the red led on the radio module blink, then blink at the same time and at same frequency the ground module red led, although with a very weak light. Thanks in advance

[@Painless360]

Sounds like the airside radio isn't running at the right baud rate and flash both with the latest firmware. I'd recheck that part of the setup first (9:40).. Also, swap the tx and rx wires on the little cable from the APM to the airside radio if you still don't get any data and connect to the radio as soon as power is applied to the model. Don't wait too long as they seem to 'lose' the ability to connect sometimes. Hope you get it sorted. Happy flying!

[@alessandrogiannoni7420]

Painless360 Thank you Painless for the answer. Well the fact is that unfortunately I have not the FDTI interface so I can not, for now, flash the airside radio. Howewer I can not flash the ground radio in Mission Planner because it fails with the message "Failed to identify Radio". Now I try to swap the tx and rx wires on the little cable. Thanks

[@Painless360]

I'd strongly suggest you get an FTDI connector and a cable to help here as I couldn't get my radios to work until I flashed both sides.. Best of luck.

[@alessandrogiannoni7420]

Hi. But with an FDTI connector I can flash the airside module. Then can I also solve the issue that I can not flash the ground module? I will buy an FDTI module. Thanks.

[@jeffdyck131]

Painless360 Further to above, no FTDI cable was needed for my modules as mention in posting above. Just installed 3DR telemetry to HK APM 2.7 board and all is working just fine. Thanks again.

[@RcBuddy]

Thank you very much, useful info.

[@robertomariscal]

Hello, i finally got my radios plugged correctly, I can not update them or load settings on mission planner i keep getting invalid comport or in use note. i set it to 57600 but nothing happens it is in auto tho, any help would be grittily appreciated

[@Painless360]

Roberto Mariscal Does this happen on the groundside radio too (the one with the USB port)? What troubleshooting have you done?

[@robertomariscal]

Hi! I finally got it working it was not to the ground radio, it times that the RX had to go to the TX so I switch the cables and finally got it working. than you very much

[@eclairj366]

Hi guys, I have 2 sets of temetry 433mhz, and I have clicked upload firmware (local) on both sets :( now the air radio is solid green and the ground station blinking, I guess I have updated the firmware to the ground station only ? is there any way of updating the air telem module without a ftdi cable ? Thanks :)

[@eclairj366]

alan york P.S, I am using pixhawc fc. Thanks

[@Painless360]

Not that I know of. Maybe another trick on the web. You really need an FTDI Basic adapter. You use them all the time flying multirotors.. Best of luck,,

[@eclairj366]

Thanks for getting back so quickly mate, I have been searching lol, Thanks

[@johncarr123]

Does the new mission planner update the firmware for the remote radio now over wireless?

[@Painless360]

What makes you ask that Jon?

[@johncarr123]

Painless360 Well I tried doing that on the tri copter I built and it worked. I was able to push firmware over wireless to the remote radio on the quad. I also tired this method on the small bug copter I am building now and it worked perfectly.

[@Painless360]

Very interesting, I will try that on the next set of radios I configure. Thanks for letting me know!

[@HighDefinitionOptics]

Hey there! I need help! My 3Dr from ebay is working perfectly with windows and mission planner over usb connection. But when i try to use it with android droidplanner 2, there is no way to get a connection. Always mavlink error. I think that my Android Phone (Nexus 5, 4.4) does not recognize the 3Dr usb ground module! Any suggestions?! Maybe a driver problem because Android cant read ftdi r232 usb uart? -Michael

[@Painless360]

Some android devices do not provide power through the USB port and provide true on the go (OTG) support. Samsung Tab 3 doesn't but Samsung Tab 4 does, You will also need the OTG adapter for the tablet/device you are using. Hope this helps.

[@HighDefinitionOptics]

Painless360 dude i conmected the ground module over USB otg how else should i connect it ;) it also seems that the module is powered because the green LEDs are on

[@Painless360]

Good to hear, most of the issues are down to a lack of power. As I've not got an android machine here that supports OTG, I can't suggest what's next. If you get it to work I'd be interested in the answer.. Best of luck.

[@CrixyTnT]

hi information do you know the usb ground module pinout im trying to connect it with a bluetooth module pls help

[@Painless360]

ras4q2001 I've documented it using the 3DR radio pinouts so you can see what the pins are on the APM. See dl.dropboxusercontent.com/u/67301981/APMRadioPort.jpg I would be interested in a video of it working when you've finished as I've been thinking of this myself. Happy flying!

[@CrixyTnT]

Painless360 ok let me explain i'm not talking about the pinout on the apm or the air radio i want to know the pinout from the usb end (ground module) the order of the setup i want is bluetooth to ground module then ground module to air radio meaning i'm using a BEC to power the bluetooth and the ground module so i made a female usb connector to plug into the ground module usb so there are 4 wires on the female usb connector what i want to know is the pinout from the usb end i don't have a multimeter at the moment to check which wires are positive or ground rx or tx i need some help i hope you understand what i'm trying to do much thanks

[@GuInHoWw]

Hi buddy, i accidentally updated my ground radio unit from 1.7 to 1.9 firmware and now i can't update the air unit too. I have the ftdi and both blink green led when powered separedly, when powered together, both become solid green but no connection on MP. When i try to update firmware using MP or 3dr config tool, it says "failed to identify radio" and when i try to load settings it says "failed to enter command mode". BTW, i'm using a chinese 915mhz 3dr radio from aliexpress. Could you help me? I've tried almost everything, read a dozen pages/forums, saw another dozen videos but nothing worked. Thanks and keep up with your GREAT videos.

[@Painless360]

Thiago Arecippo The only way I know that works is by using an FTDI Basic adapter to connect the airside radio to the USB on the PC (as shown here) and forcing the update into the airside radio. Hope it helps.

[@GuInHoWw]

I've tried with the ftdi adapter normal way and forcing bootloader and nothing. It stops when send command ATI, seems that is the command to recognize the radio. I think that it is giving me this error because my radio is a chinese clone.

[@ibrahimkhalil7315]

Hello Painless360. First, thanks. Million for your indispensable videos. I am able to build quadcopters (two so far) solely because of you. My question: Can these 3DR radios work with FC boards such as the Seriously Pro F3 and F4. Thanks again.

[@Painless360]

+Ibrahim KHALIL thanks for the question, you know what? I've not even tried. If you get it to work do let me know. Happy flying

[@lorcankelleher5434]

Do you have to flash the airside firmware? Sorry I was a bit confused by the part with the multiwii firmware board. Is this absolutely necessary or only if you're having problems? Cheers.

[@Painless360]

+Lorcan Kelleher only if they don't work..

[@lorcankelleher5434]

Painless360 thanks a million!

[@lip03pd]

would this 3dr work using droidplanner on my phone? if i used a usb adapter to my phone?

[@Painless360]

Possibly, depends if the USB port also supplies power. We've not tried it here though. Let me know how you get on. Best of luck!

[@jasfer4321]

Hi! Can I calibrate my board through telemetry?

[@Painless360]

jasferb Yes you can - see me do it in this video - kzbin.info/www/bejne/n5-WhYqEh8h5sKs about 20:10 Happy flying!

[@zaidshakil]

What should be the baudrate set up on the APM?

[@zaidshakil]

also, do i have to power the APM from a different source? cause i dont seem to get a heartbeat when they are both connected to my computer

[@Painless360]

Sorry, I don't understand you're question..

[@zaidshakil]

i wanted to know what baudrate i should set up on the APM2,8 or it does not matter? And for the telemetry modules to communicate, will the USB power do? Or do i need to connect the apm to an external power source?

[@Painless360]

All of the steps to get them working are shown in the video. We also install later versions of them to a Quanum Nova Pro in that series too. Best of luck!

[@guidovanderreijden4208]

thx man helped me out so mutch

[@Darus2013]

will this work in part with the osd board?

[@Painless360]

Not always, there is only one telemetry port so you normally have to choose between them. The Pixhawk ahs more telemetry ports to support this. I've heard of builders doing it and some running into problems with overloading the output pins on the board making both unstable. Best of luck!

+Painless360 how far is the range of mavlink? I'm I better off with osd? I bought both just waiting on the mavlink.

[@Painless360]

The OSD is limited to the range of the FPV signal, the lower frequency for the telemetry radios will give you a lot more range normally.. Best of luck!

433mh is for Europa as far as i know

[@pjpeterchen1]

Is this fit for V2.8?

[@Painless360]

Should be. Best of luck!

how to do live streaming from quad copter to my android?

[@Painless360]

+Danial Abid if you google search that you'll find lots of apps, hardware, and KZbin videos that cover it. Devices like this are what most people use - www.banggood.com/5_8G-OTG-FPV-Receiver-UVC-Capture-Card-Apm-Pix-for-Android-Mobile-Phone-p-1128907.html?rmmds=search

m building F450 controller APM 2.8...can i use 3dr video tel?

[@seanzacharyuy7647]

Where can i buy this?

[@Painless360]

If you use Google you'll find lots of places, eBay, Banggood, 3DXR etc..

[@seanzacharyuy7647]

Painless360 thanks I found one

[@Tryin2FlyII]

Hello, I ordered My APM Set and ended up with 433Mhz on the 3DR set not the 915 Mhz that I need- even after checking with the vendor (Bang Good) they don't stock 915Mhz? even though it shows on the site? anyway anyone have a 915 Mhz that they want to trade even for a 433 Mhz 3DR set as it is no good to me in the USA I could send it back but thought I would check this way first & might get lucky that someone had the same thing happen in the UK? and we could just trade? keeping my fingers crossed

[@noahdenzel]

Does this also work using Linux

[@Painless360]

Yes it does, search for 3dr radio Linux to find the details and drivers.

[@noahdenzel]

Thanks dude you sir are awesome!!!

[@Painless360]

Thanks Noah! You too!

So I just need a 5 pole to 5 pole? Is this what I need? Are the pin-outs OK? store.3drobotics.com/products/df13-5-position-connector-10-cm-1-2-3

[@Painless360]

Check what is on each end of your radio. I had to get a 4 pole and 5 pole cable and use both to make one that worked (see 2.50 in the video). Best of luck with the build..

Thanks for the "external" radio guide Tip.. i dint have a FTDI adapter and i didnt want to wait for one to ship.. so i made one out of a arduino uno witch was laying around the house www.instructables.com/id/Arduino-Examples-2-Use-an-Arduino-as-a-FTDI-Progr/

[@Painless360]

Nice! :)

[@ich3210]

I needed to insrtall theese drivers: www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

[@Painless360]

ich3210 Just so you know a new video on the 3DR/MAVLink radios is coming out on the channel on Friday that covers connection to an APM Mini 3.1 and some detail a little better than this video. Hope it helps. Happy flying!

[@francoisBonin-phils]

Hello , i have lost the link, i was trying to adjust airspeed to see if it can increase the range, then it happened, i think i did not click copy to the remote.Too bad!do you think that the pl2303 usb to serial will work to reprogram the remote one(it uses the prolific driver)?this is all that i have...

[@Painless360]

We used a FTDI adapter here to get one of our sets working. Best of luck with it!

[@francoisBonin-phils]

success to reconnect , using the "cp210x USB to UART" from the programming cable of my Flysky Ct6B Radio.
