      Hello folks
      Using
      #include <M5Unified.h>

      HardwareSerial Serial2(2);
      and then
      Serial2.begin(115200, SERIAL_8N1,GPIO_NUM_21,GPIO_NUM_20);

      But can't get Serial2 to communicate.
      Switched RX and TX no avail.
      Tested the slave with another device : slave works okay.

      What am I missing here?
      Thanks

        I don't why I have been klinging on to Serial2, it got me in all kind of testing out, but the solution is to use Serial 1.
