PPM input to SpeedyBee F405 V3 not detected by QGC

Hey all, I’m using AP with a SpeedyBee F405 V3, and QGroundControl. It can connect to the FC just fine, and I’ve confirmed PPM input from my TX to the FC, but QGC complains of Detected 0 radio channels. To operate PX4 you need at least 5 channels

QGC does show stuff like pitch/roll, so it appears to be communicating with the FW fine.

Full setup is:

Any solution to this. Is it true that Qgroundcontrol and Ardupilot can not detect PPM inputs?

What do you see here under RC Input?

Hi Dave,

Yes I noticed that and was confused because the Speedybee documentation indicates that the F405 supports PPM. SpeedbyBee F405 PPM Receiver Capability?

At this point i assume this is a limitation of Ardupilot/QGC, not neccesarily the FC?

Thanks

I would guess it does support PPM when using Betaflight.

Hello! I confirm PPM working with Betaflight connected on R2 pad.
