I found an interesting side project to interface with DW.? LoRa APRS using a TTGO T-Beam.? The project is here:
I have a couple 70cm T-Beams.? I flashed the firmware and configured the devices.? So far the T-Beam interfaces with DW 1.7B?
and the RPi 4 just fine with the "SERIALKISS /dev/ttyUSB0 115200" configuration.
I'm still tinkering with the setup.? Trying to figure out if/how to "route" traffic to/from the SERIALKISS device like we can between CHANNELS.
Good luck,
