No reading from RC receiver

Hello everyone,

I’m trying to connecting my RC receiver. I’m using Spektrum DX8 and this is how I connect it to Pixhawk3 Pro:

I have successful binding and can do all the calibrations on QGC. However, in Radio, all the channels are stated as “not mapped”. Does anyone know what might be wrong with my connection? Any help will be appreciated.

Thanks.

Pixhawk 3 Pro does not support Spektrum bind, how have you achieved it?
