Two external compass when only one connected

Hi all,

Noticing with my here 4, I have two external compass with the same assigned can ID of 125.

I can’t work out how to remove one of them, I should only have one. I did used to have two here 4 gps but removed one.

Now it’s still saying two but with the same Can ID?

In MissionPlanner compass section, do the “remove missing” button.
See if that fixes it.

For CAN devices I usually set BRD_BOOT_DELAY,3000 to allow them all to boot up before the flight controller starts interrogating the CAN buses.

Thanks Shawn as always!

For anyone else experiencing the same thing. It was a left over parameter and hang up from having two GPS. Resetting the can driver and parameters to do with the Here4 allowed the compass to be removed when it couldn’t see the here 4 anymore.

Then we rebooted and redid the parameters for the Here4 and it’s all normal now. Single compass etc
