 * If you use an Arduino with a free hardware serial port, you can replace 
 * the line "rn2xx3 myLora(mySerial);"
 * with     "rn2xx3 myLora(SerialX);"
 * where the parameter is the serial port the RN2xx3 is connected to.
 * Remember that the serial port should be initialised before calling initTTN().
 * For best performance the serial port should be set to 57600 baud, which is impossible with a software serial port.
 * If you use 57600 baud, you can remove the line "myLora.autobaud();".
