How to Use an IBUS Receiver on an F405WING Flight Controller

Step 1: Please check if the wiring between the receiver and the flight controller is correct.

It is recommended to refer to the wiring diagram in the flight controller manual to connect the receiver. Taking the SpeedyBee F405wing app flight controller as an example, you can refer to the diagram below:

Step 2: Ensure that the receiver has successfully bound to your transmitter.

We recommend that you refer to both the receiver manual and the transmitter manual to verify if they have been successfully bound.

Step 3: Check if UART1 has "Serial RX" enabled.

 Note: You can only enable one item in the entire UART row because a UART can only connect to one peripheral device. For example, if you set UART1 to Serial RX, you will not be able to enable Configuration/MSP, Telemetry Output, Sensor Input, or Peripherals on the same UART.

Step 4: Set the correct receiver protocol to IBUS.

Step 5: Check if your transmitter can be detected in the INAV Configurator.

Connect your flight controller to the configurator, open the Receiver tab, and move the sticks or toggle the switches to see if the INAV UI can display the inputs accordingly.

Note: For certain receivers, you must keep them at least 0.5 meters away from the transmitter to prevent the connection from automatically disconnecting
