Gateway using ATmega32U4



  • Did anyone get a serial gateway with ATmega32U4 to run?
    I read about some problems in the past using this chip...
    I need a small board with 2 harware serials to run a serial RS485 gateway. A ProMicro board looks nice 😏
    Right now my gateway runs on a mega board, but this a little too big



  • Update:
    Setup still not running as a RS485 GW 😟
    No debug info coming out of serial/USB.

    I flashed a normal NRF serial GW -> works.
    I did not define "MY_GATEWAY_SERIAL" -> works as a RS485 node.

    Any idea why just the RS485 GW feature does not work with 32U4?
