You need to install PlatformIO - you can install command-line or IDE, I only know about command line. Check this website how to install it: https://platformio.org/install Once you install it,...

OK, so it compiles and loads, can you see any output on the serial port ? Did you choose the corect RF chip: sx1276 or sx1262 ?

For me, this command went through, I use Lubuntu on x86_64 laptop. But yo changed the XPowerLib version and it works now ?

But it is alive, you can see GPS NMEA on the output, etc. ? What are the startp messages: does it say it found the power-control chip ? WITH_AXP does...

I find it strange, it does not transmit: when it says it found the RF chip and the GPS has a lock then it should transmit OGN packets. I will...

I just revised the code, compiled for T-Beam-S3 and it does transmit OGN status packets. At startup it prints: AXP2101 power/charge chip detected USB: 5.104V Batt: 0.000V RF chip detected

OK, this explaains why it does not transmit. Possibly, for this module I need to activate power line for this chip or something like that.

Which exact profile you use ?

Let's open the case in the prrroper project: ogn-tracker about turrning on power for various elements, as I suspect this is the prroblem here.

It is most likely the way the GPS is wired. How did you assign the GPS signals, did you use the config file which corresponds to this wiring ?
