ELRS rx bound with sensors data, but no stick inputs (Radiomaster Pocket Int ELRS<> BetaFPV 2.4GHz Nano RX <> PX4)

[Le_Nh_t_Huy_Tr_n]

Hi,

I’m having trouble setting up my ELRS RC. I’m using a Radiomaster pocket with internal ELRS, BetaFPV 2.4GHz RX and a pixhawk 6c FC.

At first, I solder my RX, build and flash PX4 v1.14, change some parameters (RC_CRSF_PRT_CFG && RC_CRSF_TEL_EN) according to this guide.

CRSF Telemetry (TBS Crossfire Telemetry) | PX4 User Guide (main)

This ís my parameters file:
parameter.pdf (59.3 KB)
I also update both my TX and RX elrs firmware to version 3.3.1.
My TX configurations:

My RX configurations:

After all that, I manage to bind TX to RX and receive some telemetry data like GPS, Roll, Pitch, Yaw on my TX but no stick inputs detected. That’s when I stumble upon this topic: How to bind Radiomaster TX12Mk2 ELRS <> RP2 <> PX4

I reupload my firmware v1.13.3 and change some parameters. Finally got my stick inputs !! But this time no telemetry data . And everytime I reboot my FC, I have to send rc_input start in the MAVLink console.

I’m at my wit’s end here so any help is much appreciated.
