CADDX GM3 Gimbal not responding

@rptacek

with the lowest nuber. (can be e.g. Serial 2 or 4…) Look at the description to avoid confusion.

I started another thread about how the modes work on the caddx/xf gimbals when I was testing this and found the same thing you did.

Gimbals Caddx/XF mode control

The directions it says to set all inputs to ch1 when using the uart configuration for these gimbals. The new configurator and firmware version for these gimbals though needs a mode set for each of the options on the mode chan, so low, med, high each need a mode. Ardupilot does not control these properly depending on what modes are set. It would be nice to actually use and set these modes in ardupilot so you can switch between stabalized and just pointing or what ever other options you want. E…

What I did was just set the mount mode to the FPV mode on the gimbal its self and ignored the rate setting in ardupilot.

I also struggled with how the gimbal lock mode works and had it only intermittently work with things like pointing the camera to a GPS target. I cant figure out how to change the earth reference that the gimbal wants to point to in “lock mode” but it seems like there are much more useful ways for that to work.

I think the XF mode (MNT1_TYPE 14) is for XFs larger gimbals that are similar to the siyi ones not the smaller ones they make for them selves and caddx but not totally sure.

Thanks for the tip on the SRx settings. Ill look in to it more as that might be causing a different issue unrelated to gimbals that iv been trying to figure out.
