Mavlink over TBS Crossfire not working

[Allister (Allister Schreiber)]

I just checked mine. I’m getting 20+ sensors as well. It might be a clue that FM is blanked out, but I’m not smart enough to know what it means.

I’ve been going over this post to see if there’s anything else obvious.

Passthrough telemetry over CRSF (crossfire)

This is to track development and testing of a custom telemetry implementation over CRSF, the goal is to have something equivalent to the frsky passthrough protocol. The CRSF protocol has been added recently (as of Oct 2020) to ArduPilot by @andyp1per. Like fport CRSF can carry both RC and bidirectional telemetry. The CRSF receiver can be wired to an ArduPilot FC in 2 ways, by using RCIN or by using a serial port (SERIAL_PROTOCOL=23). For telemetry support it requires the usage of a serial po…

According to the file you’ve posted, the RC_options are correct. You should be on the correct TX/RX, especially if RC link is working. You say it was working, so CRSF option must be selected in Yaapu menu. (unless you’ve created a new model or new telemetry page? This can reset the CRSF setting for the script) I don’t know what else to suggest. Move the RC link to another UART and try that? RX/TX4/Serial4?

Sorry man, if I think of anything else I’ll let you know.
