mav_sys_id change causes unresponsive system

[ryanjAA]

Describe the bug

If you change mav_sys_id to ≠ 1 you can not reboot or change anything from QGC.

manually rebooting works but then I needed to get out a debug probe to access the fmu to reset the param...

To Reproduce

Used a few different versions of 1.14 release.

Setup a plane and then set mav_sys_id to 2 or 3.

Try and reboot via QGC and you should get a failed to reboot.

I would not recommend doing a manual reboot since you need to set it from a debug board to fix it...

Expected behavior

Should work as previously and have be able to have multiple vehicles on the same network..

same on ark-v6x and main from a few days ago as per @AlexKlimaj

[julianoes]

Did you flash from the release/1.14 branch or flash 1.14.0?

[ryanjAA]

Release and @AlexKlimaj tried main. Same on both.

Pinging this for someone to take a look. Cant use more than one system on the same network/qgc instance...

Should work as previously and have be able to have multiple units vehicles on the same network..

Do you know since when it was broken? I.e. what's the last version that multi vehicle connection works properly?

[ryanjAA]

I unfortunately don’t know since the last production version we use is built on top of 1.11.3 which it still works. Skipped over 1.12 and 1.13.

@mrpollo not sure how to get this added to 1.15 board.
