Drotek red Flight Controller + Bluetooth


How can i connect your bluetooth module with the red flight controler if i have not ftdi port? (It is occuped by the USB) using i2c port?


I f you have the Drofly you can use the second serial port. You have just to enable this port in the Multiwii code.

No, i just have the first red flight controller (59€)

where can i connect? between spektrum and receiver connections? where i need to uncoment in multiwii code for second serial port?


This board has only one serial port so you can’t use the bluetooth and GUI in the same time.
I think you can connect the bluetooth on tx, rx, 5v and GND on the FC.
