Need helps on RC setup for Sentinel/VOXL2

[Neil Huang]

Hello there,

I would like to know whether I am able to setup the CRSF_RAW mode connection for Sentinel with TBS transmitter and TBS Crossfire Nano Rx?

Every time I used the command px4-listener input_rc to check, it is always returning never published.

By following the connection of the technical doc in https://docs.modalai.com/voxl2-rc-configs/#crsf, I could bind to the receiver and successfully arm the drone by using the TBS Crossfire receiver in CRSF_MAV mode.

@Neil-Huang In theory, yes. But why don't you want to use mavlink? For CRSF to work you would need to reconfigure the TBS portion correctly for CRSF and set baud rate on the VOXL2 UART to match what the TBS HW is using.

@Eric-Katzfey Thanks for the advise, how could I check the current baud rate setting on voxl2 uart?

Since I just got the sentinel recently, simply want to explore what options could I have for the drone, and if I possible I would not like to change my settings on TBS transmitter every time when bind to sentinel.

Did you mean changing the baudrate in the start script for the following line qshell tbs_crossfire start -c -p 7 -b 250000 to match the setting on the tbs side?

[Eric Katzfey]

@Neil-Huang Yes, if TBS side doesn't use 250000 then that line would need to be changed.
