S.Bus Receiver Compatibility and ESC Firmware

[A Former User]

Can’t get the connection working to the FrSky Receiver we installed, no inputs seem to be visible in QGroundControl – Is the installed PX4 firmware compatible with the FrSky S.BUS receiver?

Are we missing any settings?

The motors aren’t working, it seems the ESC Firmware is missing (fast flashing blue light) – where to get it?

Ever have any luck figuring this out? Stuck on the same issue

@NUMETRIX , in order to check and upgrade your ESC firmware, you can install the latest VOXL2 SDK, which comes with voxl-esc tools.

scan:
voxl-esc scan

upgrade firmware:
voxl-esc upgrade_firmware

for reference:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/scripts/voxl-esc?ref_type=heads

(the voxl-esc tools are installed to /usr/share/modalai/voxl-esc-tools/) by the SDK. You can call the python scripts directly from there as well (as opposed to using voxl-esc wrapper). But make sure to stop PX4 first.
