Hi,
After a long time, I succeeded to transmit a signal directly between 2 lorawan units without going through a router. but without being able to pass data
My configuration: 2 m5stack core + 2 lorawan unit, identical program.
I use the test functions:
the first m5stack, button A: "AT+CTX=868123000,0,22\r\n"
the second m5stack, button B: "AT+CRX=868123000,0\r\n"
or vice versa, it works.
Bonne journée
Christian
