Hello
I just got the FIO v3 board and I am having a major problem, I don't know if it's with the board or baud rate. Anyways when i print some serial data I can see it in the serial monitor when its connected via USB. When I use a bluetooth module without the USB cable I can pair to the device perfectly but I cannot see any serial data being printed, (the tx led doesn't even light up on bt only on usb)! I really need help with this issue, can someone make some suggestions to what can be the problem, the bt module works fine, So it might be a problem with the board or it can it be something with the 8Mhz clock, all the 16Mhz arduino boards I can see the data.
Okay I solved the problem Use Serial1.begin NOT Serial.Begin for bluetooth modules
