Could you try 223A2 through to 223A5 and see if any of these reboot?

Thanks Mike, will do (I have to go out and do the grocery shopping now though).
Do you think it could be something on the SD card?

I can also confirm that 223A6 works correctly on my 9XR-PRO. Thanks Lim3. BTW I am (slowly) starting to make progress on the basic script to control ELRS using the 9xr pro. I have it receiving the ELRS parameters and it is now displaying the air rate. Next I need to display the rest of the paramete...

Thanks Mike. I tried the new interpreter and that worked fine with the long strings I need. Unfortunately, when I flash my old 9xr pro (MOD: REVB-X) with the ersky9xr_rom223A6.bin the radio appears to reboot continuously, replaying the voice announcement continually. I also tried the ersky9xs versio...

There seems to be a limit of 52 chars on strings used this way?

Hi Mike,
I am wondering why a line like
drawtext(0,0,"------\0AUTO \0 500Hz\0 250Hz\0 200Hz\0 150Hz\0 100Hz\0 50Hz\0 25Hz\0 4Hz"[0])
causes interpreter.exe to crash?

Is the source available?
Is there a better way to display an string from a lookup?
Thanks,
Kit

Yes they do the same operation. A description of the erskyTx script language is here: https://openrcforums.com/forum/viewtopic.php?f=7&t=10325 . Mike Thanks Mike, that's great, especially interpreter.exe! I have a lot to learn yet but looking at the ELRS lua script and the ELRS C++ code, they a...

Nirvana just got crossfire shot protocol support. https://www.rcgroups.com/forums/showthread.php?3023832-UndergroundFPV-Dark-Knight-Radio/page247#post45357535 Any plans to bring it over to erskytx?

As I understand it, crsfshot is just a method for the crossfire module to report synchronising information to the radio so that latency is reduced. Since the control data is sent to the module every 4mS, this may provide a latency reduction of an average of 2mS. Does crsfshot provide anything else?...

Thanks, I have now flashed it using STLink.

LiM3, thanks so much for that info. One last question, how did you flash your r9m the first time? I imagine the new bootloader could be flashed using the sport in maintenance mode in erskyTx on the 9xr pro, but imagine you had to use an STLink or FTDI to flash the firmware without openTx? This link:...

Many thanks LiM3!
Now I see that there is indeed a Xfire protocol option in the R222 version of ersky9xr I am currently running.

I wonder, is there a basic script available to control ELRS, setting the power etc similar to the ExLRS.lua script?

That's great!
Many thanks for this very helpful description,

Dumb question here. I have a 9XR-Pro and am thinking of buying a RM9, but I can't find a description of how to update the RM9 module firmware (if needed, say to the flex version) without using a Taranis. Does the r222d2 ersky9x version support flashing the RM9 via the 9XR-Pro SD card, or do I need t...

Thanks for the info. I was considering just running the code that looks for the SPORT data and timing out after a while and dropping into D mode. However, someone has gone to the trouble of writing a function especially to detect the presence of D type telemetry by looking for a "D-type header&...

That's what Lorenz just suggested I do. But I don't understand how the autodetection would ever work with my D8R-IIplus (which is flashed with the D8R xp firmware) since it relies on serial data coming out of the receiver to detect the baud rate etc and there is none. Would the Taranis be generating...

After getting a development environment working for the PX4 firmware, I did some debugging and found the problem was in the PX4 firmware where it was trying to auto-detect whether the telemetry was SPORT or D-type. It was always failing to detect D-type telemetry. I now have a fix for that problem -...

Hi, I started using the PX4 firmware on a PixHawk flight controller a few years ago. I had it wired up to transmit FrSky D-type telemetry back to my 9XR Pro. Early in 2016 the PX4 developers changed the format of the Frsky telemetry a bit, as far as I can see to send the flight mode back as TEMP1 da...
