Flashing ELRS doesn't have to be scary! Complete guide to flashing ExpressLRS for newbies

[@drakeh2344]

old video but for anyone new here, I have been trying to figure out this shit for almost a year now (much time was spent crying and contemplating selling my drones) But this video somehow saved my life. Follow this advice, future fpv pilots, and figure out how to match the ELRS versions on your quad and radio and you will be saved. I was so excited after binding this and getting good signal to the goggles and radio that I ran outside for a flight, and promptly hit some powerlines. But all is okay haha

[@captainbritain6737]

Oh my goodness! It bloody worked first time! I can’t believe it. Built it, flashed it, bound them and armed them in about an hour or less. Virtually no fluff even on a Mac. The only issue I had was with getting my Mac to connect to the Wi-Fi. THANKS!!! Can’t test it yet though as late in even.

[@BaconNinjaFPV]

I really hope it worked out in your testing!!! Also, I am very happy to hear you got it first time and this vid helped you out on it :)

[@53roger]

I appreciate the info in this video and your time doing it. I had purchased a RM Ranger and 4 receivers this past winter but because of a nightmare last fall trying to get a Betafpv tx an rx up and running I kept putting it off.This spring i had watched 4-5 videos (including yours) but hadn't worked up the courage to dive in again. But today i took the plunge. It took about 6 hours to finally get it all running!!!??? Unbeknownst to me my laptop (wireless) was not recognizing the wifi signals from the ELRS equipment and all along I thought I was doing something wrong (same as last fall). What was crazy was the laptop was/is being used daily for wireless to access the internet so I logically thought it was ok. Long story short I was able to get to another computer and discovered it was the laptop causing all the problems. After I figured that out, I had the Ranger, and 2 rx's up and running in about 20 minutes. thanks again.

[@barry_dalive]

Bravo, Bacon!!! Very well presented, detailed and concise!! Thank you so much. This is officially the best ExpressLRS tutorial on youtube!!

[@BaconNinjaFPV]

Thank you sir!!! It was a whole lot longer than it had to be, but I just wanted to put as much detail in there as I could to keep people from getting stuck on anything they didn't have to be stuck on. The actual flashing takes like 5 minutes, but my rambling took another 35 :p

I just want to make you aware when I first started looking into fpv the main accounts kept popping up and filling my recommended. Now that I’m actually building, I am referring to all of your videos without any questions after watching them. I appreciate the great detail and thoroughness. I feel like I have an understanding wether it’s updating firmware to setting up my HDZero. Next I’m going to be looking up how to update and setup the HD Zero goggles. I sadly ran into an issue where my freestyle VTX video cable wouldn’t reach to my runcam only a half inch short… so now I’m waiting on the 250mm cable which is more than double the length. I was recommended the speedy bee Master 5 but wasn’t aware of the length. I’m still happy I haven’t had any hiccups besides that

Thank you! This help me getting through all the problem I have as beginner. I just succesfully bind my first drone with Jumper T Pro I purchased earlier

[@GTARC_au]

Good info mate. Don't forget the bind process. Most newer elrs receivers can enter the bind phrase be powering on and off the FC 3 times in quick succession. This will force the FC to enter bind mode. Don't bother typing bind_rx into the CLI of betaflight....this simply wont work. Also make sure that the ELRX RX firmware is the sameas the ELRS TX firmware. If not then they will also not bind.

[@FREEDOMFPV84]

well im back it worked i can now fly thank you for this video cant wait for the first flight you where very helpfull

[@BaconNinjaFPV]

I have found that there are absolutely some instances where you really can just hit the bind command and be off to the races, but that is pretty few and far between right now, lol. Since ELRS recently released the 3.X version, which is what is on your boxer since it is so new, and some quads are still shipping with 2.X versions there are lots of mismatches going on which keep that whole simple bind process for working out of the box. Hopefully after some time things start shipping with 3.X and we can get back to that....or they will just release 4.X and it starts all over again, lol. So glad you got it going!!!!

Bacon, thanks for the video..very clear.. I was good up to time 30:59 where you connect your laptop to the Txmtr's Wifi access point.. My Win11Pro desnt have wifi .. it's hardwired via Eth to the Gateway Router ( which does). I can however see the "ExpressLRS Tx" on my iphone so I will try to get the files over to it and try again later..

[@BaconNinjaFPV]

That is exactly the way I would go with it! Upload that firmware to your phone via iCloud and it should be pretty easy to connect up to it with that for the flashing bit :)

[@patrichcerpa2923]

Hi Bacon, I just wanted to thank you for the video, after a lot of errors, during the firmware build, platformio, compilation and drivers, the only thing that worked for me was to ask my wife for the computer and try to see if it worked better there (mine, although better in hardware, has been a nightmare regarding to drivers.). That's how it was, but it helped me a lot to do the update with WIFI and thus avoid at least the connection errors due to drivers. Finally, after 4 days of trying, I have my first drone connected to my transmitter.

[@BaconNinjaFPV]

You are very welcome! The Wifi method seems to be the most consistently working option as far as I have found. I tend to do a lot of firmware flashes on these things, and most of the time USB works out...but sometimes it just doesn't for some reason. Wifi is the way for sure!

Gday Bacon, I really enjoy your tutorials, I am having troubles myself, I noticed in you lua scripts you had v2. And v3. Elrs, can you have both scripts configured at the same time so you can bind to sdi elrs on the whoops and then be bound with your other quads that have a stand alone reciver, I have spent hours and days reading, youtubing, I get a little funny in the head and everyone has different takes on this. I do feel like I am learning, I am definitely not flying which frustrates me, anyways, I appreciate your efforts... cheers 🙏

[@CarlosRodriguez-vg2ob]

Great VIDEO. i do have a question, in the GEPRC site says that for my drone which is the "GEPRC Tern-LR40 HD O3 Long Range FPV" the receiver for 2.4 elrs is "GEPRC ELRS24" so when in ELRS configurator and i want to flash the receiver (not the controller) the options are "GEPRC Nano 2.4GHz PA100 RX", "GEPRC Nano(SE) 2.4GHz RX" and "GEPRC Dual Diversity 2.4GHz RX" do you have any idea which one is it?

[@scotboy1297]

Good on you,Bacon, nice video and thoughtfully brought.

[@billmcdonald4335]

I flash my TX using UART, and I run SPI-based receivers. It's an extra bit of fiddley-work with the Happymodel ES24TX Pro module. Gotta take the top plate off to access the USB port, and configure some DIP switches before flashing. I'm a bit of a stickler at running the latest firmware, so I run BF 4.4.2 and ELRS 3.3. I doubt I'll go further with the firmware, as the FCs are 411s which don't have the capacity to take BF4.5 without some phukkery.

[@zeta7SoloFPV]

Great video. I just got a Radiomaster Nano to put on my Zorro 4n1. After I get the luascript and everything flashed I should be able to connect it to my phone or pc via bluetooh for simulation usage correct? thanks

[@BaconNinjaFPV]

you sure should! The RM nano should have the bluetooth capability and you should be able to pair it from within the LUA after you get everything set up. Now some devices don't like the bluetooth controller emulation, but it is pretty rare that it doesn't at least register the inputs correctly. Switches may be a little rough, but sticks should be golden!

[@nyclassic4ever130]

@ 27:29 building the RX firmware BIN. So the one with the long name is what we will flash to the RX but what is the other "firmware.bin" file created? Isn't it the same thing? I was always confused about that.

[@BaconNinjaFPV]

you know, im not sure what that other firmware.bin is for really. I have always just assumed it was some resource left over from the compiling process. I imagine it is the base firmware that gets used to generate the board specific firmware with the longer name.

[@crash_and_burn_fpv8870]

Great vid! i have the hm x12 aio spi and its kompatibel with the elrs 3.0 i have betaflight 4.3.1 that suport elrs 3.0, also can you show backpack how it works and how to setup?

[@BaconNinjaFPV]

I will absolutely show the backpack soon :) Going to pair that one with making it work on the HDZ goggles if I don't have to send them back before I can get to it. Yeah Happymodel does have that unofficial branch of Betaflight that supports ELRS 3.0, so that makes it a bit easier with that board!

[@bsr3280]

Do you have to have a control board or is there ELRS receivers to just use Chanel’s or the radio to control the model?

There are ELRS receivers with PWM outputs so that you don't have to always use an FC. Matek and a few other manufacturers sell them :)

Hey Bacon, I have the nano radio master version. Can you flash 2.5 to it as most of my drones have 2.5 receivers. Great video.

[@BaconNinjaFPV]

so, unfortunately the minimum firmware version for a module is based on what was out when it release. Since the ranger line came out when 3.x was available, that is the oldest builds it has :( The only choice will be to update you fleet...which hopefully isn't too many SPI based quads.

[@ntorres1966]

@@BaconNinjaFPV Thank you.

Great video! Just ordered a Mobula 7 and a ranger nano. But got a bit turned off now cuz I guess it's spi based. Does that mean I have to stick to old firmware in the module to get it to work? Don't know if the mobula will handle BF 4.4...

[@BaconNinjaFPV]

hmmmm, the extra stuff on the SD card shouldn't be causing you any trouble with the receivers disconnecting. Are they disconnecting when you are on USB power or with a pack plugged in? Sometimes they act funny if they aren't quite getting the full 5v they need, or sometimes even when the amp draw they have available isnt sufficient.

[@BaconNinjaFPV]

hmmmm, did you get it with a bind and fly or was it something you installed at one point? If that is what your firmware says on the web page, you should be able to just build for the same target in the configurator and I think they have some generic (or DIY options) in there for those instances. I haven't run across a generic in the wild though, but it is possible that some vendor somewhere built a board based on the reference design and just used the generic target to get it going.

[@SunriseWaterMedia]

@@BaconNinjaFPV It's a bind and fly quad. I ended up trying the DIY option and it worked out. 👍 Thank you.

[@Wontworld]

When I connect to my RX wifi, as soon as I connect, it slow blinks on the rx and seems to disconnect. (The ELRS page will popup if i'm fast enough, but It doesn't keep its connection) Do you know what this can mean?

[@BaconNinjaFPV]

hmmmm, usually that either means the RX doesn't have enough power to run in wifi mode very long, it is getting hot, or there is something up with the firmware on it. Are you using a pack plugged in or powering over the USB to do your flashing? If so, you might try using the betaflight passthrough flashing method in the ELRS configurator instead. To do that you will need to check the BF passthrough bubble and make sure your quad is connected to the PC with BetaFlight not running at all. Then when you hit build and flash it should take care of everything for you. The passthrough method doesn't always work, but in this case it is well worth the shot.

[@Wontworld]

Currently any way of checking what fw I last flashed on my module? I know I left it on 2.something but how can I check?

[@BaconNinjaFPV]

If you are talking about the TX module, that info is in the LUA script. I don't remember where exactly off the top of my head, but I feel like it is right on the page at the top or bottom somewhere. As for the receiver, I believe you can get that in the LUA under a menu item as well, but otherwise you can just connect to it via wifi and get that info from the page where you would normally go to load new firmware.

[@ronfox8385]

I hope you see this!! I am following the video and got to the point of selecting expresslrs from the list of tools and when i do i get a blank screen that just says loading at the top.

[@BaconNinjaFPV]

Ah, that one does happen! Usually it means you don't have the correct module selected in the model settings for the current model your radio is set to. You will want to go into the model settings and make sure you have it set to either use internal or external RF, whichever one your ELRS transmitter is in. Once you have that set up, it should load properly :) if that still doesn't work, there are some more advanced baud rate settings to double check as well.

[@BaconNinjaFPV]

You should for sure update your LUA whenever you build a new flash for your radio :) Partly because that is the easiest time to do it with the little button that comes up in the flashing screen, but also just to make sure it can talk to your transmitter in a way that the transmitter expects after being flashed.

[@dondupuis4007]

How did you get to the internal and external RF?

That part is going to be in the settings of your model. Getting to that is a bit different for different radios, but once you pull it up you will want to edit the model you are trying to configure and that internal/external option will be in there :)

Because the version on my radio is 2.0...any help would be great thanks

[@BaconNinjaFPV]

sorry it took me so long to see this...YT's comments have been really janky for me lately :( I would be willing to bet that your cineape25 has a v3 version of ELRS and that isn't going to bind up with a v2 version on your lite radio...unfortunately.

And then in SYS the hardware page the internal rf is Type CRSF and Baudrate 1.87M.

Any help would be much appreciated.

[@BaconNinjaFPV]

Is this the first flash on your boxer, or had you already flashed it previously? If this isn't the first flash, did you happen to set the home wifi settings in it? If so, it won't broadcast wifi anymore since it will just connect to your home wifi. The only way to find that when using that setup is to start wifi, then close ELRS configurator, re-open the configurator, and wait for it to show up in the available devices section at the bottom. If it is your first time flashing that boxer, then it is for sure a more complicated issue.

I'm a total newb trying to set up a tx12. I was told I dint need to flash it. I'm working with fixed wing no quad. It's all very confusing. I'm just trying to get the menus straight for when I get the rx to bind it properly.

[@BaconNinjaFPV]

As long as the receiver and transmitter are running the same base version of ELRS (2.X or 3.X) then you "technically" dont have to flash everything. You would just plug/unplug the power to the receiver 3 times quickly which puts it into bind mode, then hit the bind button in the ELRS LUA script to get it going. Personally though, I would still flash it just to make sure everything is on the exact same minor version too.

[@capnhardway]

@@BaconNinjaFPV thank you, that breaks it down a little more clearly than what I've seen. Should have rx any day will give it a try. Thank you!

[@xXSubScorpionXx]

I got problems to bind my brand new Nazgul5 v2 F7 to my LiteRadio 3. I've heard I must flash both receiver and RC to make them compatible, but I'm not being able to understand to which version I should flash them neither to understand how to flash it.

[@BaconNinjaFPV]

So with the Lite Radio 3 Pro you will probably want to pull the user manual from BetaFPV and that flashing process will most likely be over USB. As for the quad though, you can totally do that one over WiFi. I would go with version 3.2 since it is the newest, and there are targets in the ELRS configurator for both the radio and the quad's receiver in there. For your quad, there are only 2 options listed under the iFlight 2.4g selecting in the configurator, and you will want the RX :)

[@xXSubScorpionXx]

@@BaconNinjaFPV yeah man, I had to flash my LiteRadio to last version, and the RX to the 2.5.2 that is the last version compatible with that RC, it sucks. Finally binded it, but screwed it up and erased every single drone setting. Could get the dump file, but motors make a weird noise now

[@ghostrot]

Could you put one binding frase in the tx a d a diferant one on the module to fly my sons drones too ?

[@BaconNinjaFPV]

unfortunately it will only work if the binding phrase on both the TX and RX are the same :( One way to do it though is the loan model feature! He can use loan model to let your TX temporarily control one of his quads. here is some info from the ELRS site on how to do that: www.expresslrs.org/software/loan-model/

BACON. Need help I flashed wrong target on foxeer rx. RX will not light up now. Can you help?

[@BaconNinjaFPV]

That is a tough one! If you flashed a target that wasn't made for your board and can no longer access it to re-flash, the only way that I know of is with the HappyModel ELRS recovery tool. It is basically a serial adapter that you solder up to the receiver and flash it at a lower level that doesn't require successfully booting the receiver first. If I remember correctly, they are pretty cheap to pick up and always a good tool to have laying around.

Hi Bacon. My TX isnt broadcasting a wifi signal.... its a Onboard UART ExpressLRS 2.4GHz Receiver on my crux35 v2. Neither my phone nor PC can find it

[@BaconNinjaFPV]

Hmmmm, hopefully it is something simple! What kind of light pattern are you getting on the ELRS receiver light? It should be green and near the edge of the board. The one toward the middle is the status light, so it will kind of do its own thing.

[@Pappagar]

@Bacon Ninja FPV hi bacon, I figured it out. My phone never did find the signal, but I had to hold the drone 6 inches from my PCs wifi card lol. Any further and the signal would drop! Now I'm having an issue where when I plug my drone into betaflight nothing happens. No lights or com recognition. I even tried impulse rc and driver updates. Not sure if I had flashed it wrong....

OK so I have the files to update my radiomaster rp3 rx but when I click on choose file nothing happens. The only way I was able to bind my boxer to the rx is with model match.

I did a little video on troubleshooting ELRS that may help you out. It is a few weeks back on the channel, but it takes a look at the blink codes on your receiver to help point in the right direction as to what may be going on :)

[@frnkguard1]

@@BaconNinjaFPV thanks 👍🏻I found the instructions on all my gear I’m gonna start there

[@ghostrot]

How do you know if its a spi based quad ?

[@BaconNinjaFPV]

The best way to tell will be to take a look at the receiver tab of betaflight. In there you will either see Serial UART or SPI selected in the first drop down on the right side. Other than that, you sometimes have to dig through the manufacturer specs for the board since SPI receivers are integrated on them. It can be tricky though since UART receivers are getting the same integration more and more...the Betaflight way wont lie thought :)

I brought up my issue in ExpressLRS Discord channel, I was having issues only with 3.4.X, 3.3.2 works fine……at least for me

[@flat-earther]

I wish I could configure my 3 position arming switch as 1. Disarm + VTx Pit Mode 2. Disarm 3. Arm that way I wouldn't have to use a separate switch specifically for pit mode. is ELRS the reason this can't be done? or is there still a way to do that?

[@flat-earther]

Actually I found out how to do it. On EdgeTx I edited the channel I use to control Pit Mode which in my case is channel 12, I changed the source of that channel to be the 3 position switch I use for arming, and then on modes tab in betaflight configurator I used the arm switch as a source for pit mode! Initially I wished the 3 position arming switch on my RM TX12MKII would have been 2 position, but now this is a perfect use for it! But I noticed that to arm I first have to leave the switch in the regular disarm position for a moment so it has time to go out of pit mode, before I switch it to armed. Otherwise it will arm and stay in pit mode.

[@tombusby2333]

I just went through this and had to use the usb of the module to get it updated. I have a TX12 original with external Happymodel module. I converted my TX to EdgeTX cuz that was recommended. I have the BetaFpv Spi Aio 1280 board and use BF 4.4 Everything works and the drone flies well. Sadly however I cannot get my TX switches to work. I only have Aux2 and Aux4. I have my Arm always on the left lower switch...Aux1 but when connected in BF I cannot use those switches....wtf went wrong here? I cannot finda anything on the goggles to fix this...can you provide any assistance.

[@dustinwilson492]

You have to assign your switches to a channel. Channel 5 for arm channel 6 for modes etc. You can use the model wizard or go into the tab in your radio and add them manually.

[@BaconNinjaFPV]

Yeah it does sound like maybe your channel mixes aren't quite in the place ELRS is expecting. Unfortunately I didn't cover that in the video because it was already soooo long, but you will want your arm switch on channel 5 as that will show up as AUX1 and every channel beyond that will be the next AUX down from 1. You will want to go into your model on either the radio or the model wizard if you feel like doing it on the companion PC app and see if that is lining up.

[@BaconNinjaFPV]

It sounds like you will want to flash the ELRS preset for the packet rate you are using in he BetaFlight presets tab. Without those, the RC smoothing in BF 4.3 up can make things pretty crazy, lol. You will want to go into that tab, filter for radio link with the left most drop down, then find the official ELRS one for the packet rate you have set on your radio. Flash that preset with the couple of questions it has answered and I bet it flies much better! Did you have a crossfire preset flashed before now or were those just running without a preset when you were on crossfire?

[@StringbeanFPV]

@@BaconNinjaFPV they were running without presets. Didn't even know you had to do presets for this. I'm going to try this right now if I understand correctly lol this is why noobs stick to tbs. Simple as pushing a button ugh 😩 lol I'm not giving up though I will master the ELRS black magic

@@StringbeanFPV ah ok, that makes sense. Usually since crossfire runs at slower packet rates, the impact of that RC smoothing isn't as big as it is when you start running the packet rates ELRS is capable of.

[@BaconNinjaFPV]

Hey, thanks for the sub! To use the method I am showing in the video, you are going to want to use the build button rather than build and flash. Using build and flash expects that your radio is connected over USB and has everything set up to flash via that method which is why you are getting a com error...which kind of rarely works if I am being honest, lol. I chose the wifi method for this one since it has a very high success rate compared to the bind and flash options.
