Appreciate this comment. You've captured the very reason the channel exists: To help out.

I really struggled to update my radio and I thought I had 'bricked' it. "If it ain't broke don't fix it". However, with the help of your videos all is well and I have a functioning radio again. Thanks.

Phew--crisis avoided. Wait till you see the video I'm uploading right now...it might give you night sweats.

@@RCVideoReviews What was confusing me was the channel order, the radio being in mode 1 when I fly mode 2, all my settings were mis matched. Different channel order between OpenTX and multi protocol module. It may be worth making a video explaining how this all needs to be set up and matched? Thanks so much for all your help.

Thanks mate that's good info....the FlySky AFHDS 2A update looks interesting.

I asked Radiomaster concerning the Conformity of Compliance when updating the internal multiprotocol update.: “As far as we know not” was the reply. I ask the team now for an statement from the developers of the internal multiprotocol module.

[@RCVideoReviews]

It makes sense to me they would say that. They sold it compliant. If the user does something that makes it non compliant they wouldn’t want to be in the middle of that question. You can always leave the firmware alone and remain compliant with the initial attestation.

[@guuskoelman8254]

@@RCVideoReviews Thanks for your quick answere

[@guuskoelman8254]

Maybe a silly question: Has changing the software in the internal multiprotocol module influence on the properties of the transmitter that gave the transmitter there conformity of compliance from july 2020

[@RCVideoReviews]

I don't have any way to definitively answer that question. If you want to dig in, head over to the MPM project page on Github and either check the source code or ping the developer pascal. My *guess* is that the developer would not change EIRP levels. Not to say a user couldn't. I have a video on how to compile your own MPM.

Your videos make learning for the beginner to OpenTx or in my case EdgeTx very easy. I just did a module update and all is well but I don't know what all the different abbreviations are for the DSM protocol. I currently have all Spektrum radios so I'm focusing on those for now. Can you tell me what 2 1 F, 2 2F, X 1F, X2F, AUTO, & R 1 F for the DSM protocol? Thanks again for all your help and I will be ordering some shirts next - your one of the few that has long sleeve T-shirts!!!!

I’m Spektrum illiterate. The only times I’ve used DSM I just select auto and the rx sorts things out with the rx when I bind. Feel free to hop on my discord server and ask though. Plenty of Spektrum users there.

I think your videos are great. I just updated my TX16s by copying this. It tells me the version is now the 2.3.9(3). When I go to Tools, all protocol options(FRSky, Graupner, etc) have disappeared. All I see is 01 Spectrum (INT). Where did they go? How can I get them back? Can you help please?

[@RCVideoReviews]

Updating the MPM firmware shouldn't do anything to your sd card contents where those tools are located. Odd. Anyway, go here: www.open-tx.org/downloads Find your firmware revision, download the sd card contents for your firmware and unzip to your SD card. That should replace any missing tools scripts.

[@ammar6937]

on the latest tx16s update there's a multi. txt file on the downloads..so you know where this file goes on the sd card folders

RCVR, can you please help me. I have this TX. I've updated everything, firmware, multi-module, bound and rebound my models....etc. I've just switched to this from spectrum and love it. All my models have spectrum receivers (planes/helis). When I do a physical range check I can put the TX in low power and walk 100 meters away from the model with not problem and still have control. But if I click the "range" option and monitor the RSSI it drops to 0-30 15ft away from every model I have and gives critical alerts and telemetry lost, but I still have control of the model over 100 meters away. What is going on?

I’m not the best person to help with this because I don’t own any Spektrum gear. So I can’t provide any experience based information. You should consider joining our discord and asking there. Plenty of knowledgeable Spektrum users on discord.

To be clear my question is can I download the existing firmware on my TX16S to my new xm+ receiver and bind that way ? If I do that my old receivers and my new xm+ would all be the same .. Or will I be forced to upgrade all my receivers? I have no complaints with the firmware I’m currently using…Again thank you … 🙏

Hi,I understand there is an option where you can hard set fine tune for various makes of receivers in a config-h file. This would be be handy if using an external module in different transmitter. I found the file on the site but have no idea on how to configure it, if your able to explain how to do that would very helpful

[@RCVideoReviews]

Alan, You have to pull down the source code from Github and compile the firmware. Here are instructions for setting up a compiler environment: github.com/processing/processing/wiki/Build-Instructions Looks like you need the Arduino IDE to compile the source: github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Compiling_STM32.md Personally, I prefer linux. On linux you can add the Github repo and clone it to your local hd from the command line. If you install the developer environment in your linux distro, the IDE compiler should work with what pascallanger put up right out of the box. This is the config.h file you can edit using your own values. github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/Multiprotocol/_Config.h

[@RCVideoReviews]

I actually just went through the process and it was super simple. Follow the instructions closely and it works. The only error I found was on compiling the binary, with all options enabled in config_h, it came out to be 101% in size. I commented out two protocols and it compiled successfully at 99% in size. My compile produced 1.3.1.59 which is even newer than the release copy. multi-stm-1.3.1.59.bin

[@RCVideoReviews]

I found what you want to do: /** CC2500 Fine Frequency Tuning **/ //For optimal performance the CC2500 RF module used by the CORONA, FrSkyD, FrSkyV, FrSkyX, Hitec, HoTT, SFHSS and Redpine protocols needs to be tuned for each protocol. //Initial tuning should be done via the radio menu with a genuine CORONA/FrSky/Hitec/HoTT/Futaba/Redpine receiver. //Once a good tuning value is found it can be set here and will override the radio's 'option' setting for all existing and new models which use that protocol. //For more information: github.com/pascallanger/DIY-Multiprotocol-TX-Module/tree/master/docs/Frequency_Tuning.md //Uncomment the lines below (remove the "//") and set an appropriate value (replace the "0") to enable. Valid range is -127 to +127. Any value entered in the subsequent lines other than 0 results in a hard coded tuning value which would travel with the module from radio to radio.

Aside from that no changes nor mods. 3) No changes in sd card too 4) for the opentx it is just my observation since no button is responding and only the bootloader is working i tried flashing opentx from the available firmware and it was successful but for the multi module it says not valid firmware file. We can exclude this one as i think that is not the right way to flash multi i think it should be done in the system firmware as i need to select internal or external while in the bootloader theres no option and only the opentx can be flashed from there. 5) not using any external module. Before the emergency mode I am in internal rf>multi>Frsky>D8. So now i wonder is my power button broken?

Did you remove the battery and reconnect? Is the battery 100% confirmed fully charged? I wouldn't jump to power button if you can move the trim switches in and power it up to flash. You said you were able to flash a new firmware in bootloader so that means you turned it on right? Does it still cycle on and off or can you just hit the power button and see emergency mode?

Another problem is when in emergency mode no matter how long you press the power button to turn if off once released it will come back on and again it emergency mode. It will not shut off with the battery connected. Just a moment ago after pressing power button repeatedly i was able to get to the welcome to open tx screen so i check everything inside and all is normal i was able to flash the multi module firmware v1.3.1.65. Thinking everything is good i put back in its bix and prepare to sleep but after 5mins i heard it saying welcome to opentx 😂😱 then power it off and back to the same issue emergency mode. I ended up removing battery and go back to sleep for at least 2hours before my shift. Then i will back after work to find out what is causing it.
