    Hello, we recently had to get our VOXL2 board replaced and the returned unit doesn't appear to have the correct configuration for our original transmitter and receiver. Our transmitter is an ORQA FPV.Ctrl with a Ghost UberLite-24 module. The receiver on our Sentnel is a small white board, with one antenna port, and the word 'GHOST' printed on it. The new VOXL2 is running voxl-suite 1.4.0.

    Out of the box the system appears to be using RC=CRSF_RAW in the /etc/modalai/voxl-px4.conf file. This results in 'px4-listener input_rc' returning all zeros for stick inputs, 16 channels, and rssi of 0, and rssi_dbm as 'nan'. QGroundControl shows the channel monitor, but the sliders do not respond to stick inputs.

    When I change to RC=GHST 'px4-listener input_rc' shows the same as CRSF_RAW above, QGroundControl shows no channel-monitor section at all.

      First of all I would update the SDK to something newer. That's probably not going to solve this issue but it makes it easier for us to support you when you are on the current SDK. To help troubleshoot can you show the output of px4-qshell ghst_rc status. Run that status command a few times.

        Hello again,

        This is the voxl-configure-mpa I've got after running voxl-configure-sku...

        voxl2:/$ voxl-configure-mpa
        ------------------------------------------------------------------
                       Welcome to voxl-configure-mpa!
        
        VOXL is currently thinks it is in the following hardware:
        
        family code:   MRB-D0006 (sentinel)
        compute board: 4 (voxl2)
        hw version:    2
        cam config:    11
        modem config:  7 (VOXL 2 5G Quectel (M0067/M0090-3-01))
        tx config:     9 (ghost)
        extras config: 0 (none)
        SKU:           MRB-D0006-4-V2-C11-T9-M7-X0
        
        If this doesn't look right, quit and run voxl-configure-sku to
        set it correctly. Then run voxl-configure-mpa again.
        
        
        Continue? y/n: n
        Ok, exiting
        

        This seems to apply correctly, but QGroundControl still shows no control stick responses.

        px4-shell ghst_rc status doesn't seem to indicate that the process is running, and I've rebooted the Sentinel after using the voxl-configure-mpa command..
