STAMP-C3 problem with Serial2

  • H

    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

    Solved
    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.
