Serial over Bluetooth

Now that we verify that the Bluetooth module works with minicom/PuTTY, let's connect it to the microcontroller:

Recommended steps to wire this up:

  • Close OpenOCD and itmdump.
  • Disconnect the F3 from your laptop.
  • Connect F3's GND pin to the module's GND pin using a Female/Female (F/F) wire (preferably, a black one).
  • Connect F3's 5V pin to the module's VCC pin using a F/F wire (preferably, a red one).
  • Connect the PA9 (TX) pin on the back of the F3 to the Bluetooth's RXD pin using a F/F wire.
  • Connect the PA10 (RX) pin on the back of the F3 to the Bluetooth's TXD pin using a F/F wire.
  • Now connect the F3 and your laptop using an USB cable.
  • Re-launch OpenOCD and itmdump.

And that's it! You should be able to run all the programs you wrote in [section 11] without modification! Just make sure you open the right serial device / COM port.
