This may be trivial, but whats the easiest way to send the reply received on Serial3 of a 2560, out to Serial (0) so it can be seen on the serial monitor.
I am trying to talk to a Sena ESD110V2 Bluetooth module, and I am just trying to get it to scan what is in range, and I want to see it so I can hard code the info that comes in (just testing).
Is something like this code snippet along the right lines?
while(Serial3.available() <= 0)
myByte = Serial3.read();
echoArray[i] = myByte;
