:fire: Release Blockers Discussion

ESC Calibration Issues (PX4-Autopilot #24635): PR was updated to address discussion feedback from the last call, and is waiting on testing for @AWilkins_Ascend

Geofence Breach: Reported by Gerald during flight testing on Pixhawk 6X RT

Geofence breach behaviour different than with 1.15. Hold/Return happening behind geofence. If I recall correctly in previous PX4 versions Hold/Return happened before reaching Geofence.

RC Docs: Some boards have hardware limitations that need to be covered per board. These include SBUS, DSM, and IO inconsistencies, which we need to address. @hamishwillee we need to discuss on a call with @dagar let’s sync via discord on dates/times so we can draft a plan.

Community Q&A / PRs for Review

Precision landing issue: The issue is it shut up during precision landing. @Teddy will post an issue for it.

Can I get this looked at please - specifically confirmations of how it is supposed to work - the PR outlines how I infer it does. This is important because it is very confusing when docs and behaviour don’t match on β€œbasic usage”.

If it’s possible to discuss how to include TFLM into PX4 that would be great! This is possibly the last week I’m able to attend the devcall about this PR.
