Hi, Ashu

you probably need to use the “pc.printf” instead.

I’m using the USB Mbed programmer and it works well !

// Serial via USB for debugging only

Serial pc(USBTX,USBRX);
...
  pc.baud(115200);
  pc.printf("TTN mDot LoRa Temperature sensor starting ... \r\n");
  pc.printf("Network Address ");
    netAddress = dot->getNetworkAddress();
    for (std::vector<uint8_t>::iterator it = netAddress.begin() ; it != netAddress.end(); ++it)
        pc.printf("%2.2x",*it );

cheers
Rico
