I am trying to “sniff” the LoRa packets with a Adafruit M0 with a LoRa module and I am using the RadioHead library in the Arduino IDE. I am able to make 2 of the M0 devices talk with the example sketches, but I can not seem to figure out the correct LoRa config for Meshtastic. I have the modemConfig registers (reg1d = 0x78, reg1e = 0xC4, and reg26 = 0x00) and Freq (903.080071) set correctly I think. When I transmit from a Meshtastic device I see the rf95.isChannelActive() function change states, but I never see rf95.available() go true. What am I missing?? I have also messed with preamble length both 8 and 16, but when preamble length is set to 16, i do not even see rf95.isChannelActive() go true, so i have concluded 8 is the correct value.
Thanks for the help
