Configuring the bluetooth module

To configure the Bluetooth module, you must connect to the module with a serial link. You can either use an FTDI USB to serial adapter, or your flight controller using the Virtual COM port ComBridge.

FTDI adapter

Connect your FTDI adapter as follow. Tx/Rx lines are crossed and FTDI provides +5V.

CC3D - Virtual COM port - Combridge

 

CC3D or any OpenPilot board can be used as a pass-through device, same as previous wiring : Tx/Rx lines crossed.

CC3D need +5V in one output port to power the bluetooth module.

 

In this case you need to setup the board for Virtual com port (VCP) use and choose MainPort or FlexiPort as ComBridge.

  1. Set the following settings:
    • USB VCP Function ComBridge
    • Main Port ComBridge
    • Speed 9600 (if brand new, unconfigured, 9600 is default baudrate)
  1. Click Save
  2. Reboot the flight controller, system will ask for driver install and the Virtual COM port should appear in the Windows Device Manager.

Configure the Bluetooth device

 

Optional - connect Bluetooth & osd on a single port

Connect your Bluetooth as normal, once you have done this ONLY connect the rx of the OSD to the TX cable of your bluetooth-port (creating a y cable) ( dont forget your osd still needs power)

 

Finally, change the Port where the Bluetooth module is attached to "Telemetry".
