How to use an SRXL2 receiver with the F7 V3 flight controller？

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

It is recommended to refer to the wiring diagram in the manual of the flight controller to connect the receiver. You could refer to the following diagram.

Note 1: The signal wire(s) of the SRXL 2 receiver should be correctly connected to the flight controller. For an SRXL 2 receiver, connect the signal of the receiver to a free TX pad(instead of a RX pad) of the flight controller.

Step 2: Check if the 'Serial Rx' is enabled for the receiver

For example, if your receiver is connected to UART 2, then you should enable 'Serial Rx' on UART 2.

Note: You can only enable one item in the whole UART row because one UART can only connect one peripheral. For example, if you set UART 2 as Serial Rx, you can't enable configuration/MSP, Telemetry Output, Sensor Input, or Peripherals.

Step 3: Set the correct receiver mode and provider.

 please choose 'SRXL 2'

Step 4: Check if your transmitter can be detected in the Betaflight configurator.

Connect your flight controller to the Betaflight configurator > Receiver tab, move the sticks or toggle the switches to see if the Betaflight UI can show the input correspondingly.

NOTE： for some receivers, you must keep them at least 0.5 meters far away from the transmitter to prevent the connection from being disconnected automatically.
