How to configure the radio receiver in the SpeedyBee app?

1. Please check if the receiver wiring is correct.

Please note: For SBUS receivers, the SBUS signal wire of the receiver can be connected to any idle UART on F7 flight controllers. But for F4 flight controllers(for example, the SpeedyBee F405 V3 flight controller), the SBUS signal wire can only be connected to the SBUS pad, as shown below:

2. Use a USB data cable to power the FC. Connect the FC to the application via Bluetooth.

3. Go to the "Ports" tab, and enable "Serial RX" for the serial port to which the receiver is soldered (for example, UART2). Click "Save and Reboot."

   

4. Go to the Receiver tab, and select the correct values for "Receiver Mode" and "Serial Receiver". You should do this according to your receiver's manual. The following are the common receiver types for different brands:

• TBS Crossfire – CRSF
• ExpressLRS – CRSF
• Spektrum DSM2 – SPEKTRUM1024/SRXL2
• Spektrum DSMX – SPEKTRUM2048/SRXL2
• FrSky RX – SBUS or FrSky FPort
• Futaba RX – SBUS
• FlySky RX – IBUSTurnigy RX – IBUS
