v1.14 Release Blockers

Optical flow issue is work in progress
Needed: Testing

We need to make sure the beta release (release candidate) download via QGC works.

PWM Min Issue:

github.com/PX4/PX4-Autopilot

Tune PWM default values for multi-rotor to improve user experience

There were multiple reports of simple multicopter setups e.g. X500 where the def…ault PWM values had the motors not spinning at idle speed when arming. E.g. I assume the default minimum PWM value was 1000 instead of some reasonable idle PWM for typical ESCs. I think this should be solved before releasing 1.14 to prevent many support cases.

Tilting rotor multirotor PR - Salvatore

Having higher level overview diagram would be more helpful!
Having trouble rebasing
Why not go through the current implementation (based on v1.13), and go through high level overview of the feature?
The changes however seem quite self-contained, so the rebasing shouldn’t be so complicated.

Action Item:
Try to rebase (or cherry-pick), and let us know in the PR!

VICON problem

Note: There’s a VICON problem, which made reverting to the old version a better option. We should catch these problems and fix in main branch, to make sure this problem doesn’t arise in the future.

Could be related to unsupported MAVLink frame type, which can change between releases.

Note: Would be nice to have testing to catch these actual use cases (e.g. VICON message streaming)

XRCE-DDS renaming

Having the consistent naming is much needed, it is a good change!

Regarding the PR: https://github.com/PX4/PX4-Autopilot/pull/21476
I’ve updated the description and written the file requested in the last maintainers meeting.
I would be happy to discuss with you about that and the problem that I am facing with the rebase of the branch.
