HC-05 or HC-06 bluetooth modules can be used, it allow a short range wireless link with your board or Oplink as Rc module.
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.
In this case you need to setup the board for Virtual com port (VCP) use and choose MainPort or FlexiPort as ComBridge.
- Set the following settings:
- USB VCP Function ComBridge
- Main Port ComBridge
- Speed 9600 (if brand new, unconfigured, 9600 is default baudrate)
- Click Save
- 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
In this section you first need to find a terminal software to talk trough serial connection with your bluetooth module.
For Window systems : PuTTY
For Linux try Cutecom or PuTTY, and CoolTerm under Mac OSX
Configure your terminal for 9600 baud rate, 8 data bit, 1 stop bit & no parity serial connection.
While the configuration software above is by far the easiest method on a Windows system, Mac and Linux users will have to use command line to configure the Bluetooth module. There are many terminal applications you can choose from. One option for Windows and Linux is PuTTY, and for Mac CoolTerm. No matter which terminal application you use, connect to the COM port that the FTDI or VCP ComBridge is in with 9600 baud rate, 8 data bit, 1 stop bit & no parity serial connection.
