I’ve connected a T-Beam T22_V1.1 20210222 to the TTN and learnt the following things:

  1. The USB-serial chip isn’t properly supported on the Mac (neither Intel or Apple Silicon both running Monterey 12.4). I didn’t explore third-party drivers, but just copied the files to a Raspberry Pi, and ran esptool there instead.

  2. a. The Meshtastic firmware appeared to work, though having only one device it was hard to be sure. It doesn’t use The Things Network, so this firmware is only really useful to test the toolchain and basic hardware.
    b. I couldn’t get LMIC-node or LMIC-node-gps-tracker to work: the hardware initialization failed, though it wasn’t clear why. I didn’t spend long on them though, and it’s quite possible I was making a stupid mistake.
    c. The TTGO T-Beam Tracker worked after fixing the duplicate hal_init issue described above. It connects to The Things Network and successfully logs its location.

I hope this is helpful to anyone trying to get a simple example working.
