| 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.

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.
...
Also be sure to setup "No line end" for data sent. - Send AT command and module should answer OK on receive window
- Set name, send AT+NAMEMybluetoothName where MybluetoothName is the name you choose.
- Set baudrate using the AT+BAUD command: AT+BAUD7 set baudrate to 57600bds. (if you need 38400 you should send AT+BAUD6)
- Module answer is OK57600
- At this point you need to change baudrate and talk again with bluetooth module.
If later you need to talk with bluetooth module using a FTDI adapter you only need to change baudrate in terminal settings. |
