Radiomaster rp3 ELRS no stick inputs in betaflight

[mighty cliff]

Hi - New here!
I wired up my reciever to new fc mamba f405 mini mk4 on uart 4 and there is no stick input in betaflight. My radio (boxer ELRS) is bound to the receiver (red soild light) and I have 10 telemetry sensors.
Thanks for any help.

Besides the questionable soldering, this looks correct. Can you put the receiver into WiFi mode and show the !webui?

Connect to your transmitter's or receiver's WiFi network to access the web UI:

Update both to the latest firmware via USB/Passthrough, and make sure you have model match disabled on the model tab in the receivers webui

Doesn't matter for internal module

Show the receivers model tab

Everything looks good, try moving the receiver to a different UART
