As mentioned on the 3.5.2 release discussion we have decided to do a 3.5.3 release to fix a couple of important bugs found by users in 3.5.2. The main motivation for the release is a problem with flying without a compass enabled. If you fly 3.5.2 with MAG_ENABLE=0 or no compass attached then there is a risk that the EKF2 attitude estimator may become unstable before takeoff. This can cause the aircraft to crash.
The other changes in the 3.5.2 release are more minor:
fixed loiter radius for counter-clockwise loiter
fixed the loiter radius when doing a RTL at the end of a mission
provide reasons to the GCS when a uBlox GPS fails to properly configure
Hi,tridge,
I found that it’s more difficult to maintain the auto flight altitude in 3.5 that that in 3.4,is it?
I truly need your help.My plane cann’t maintain the alt in auto mode,firmware 3.5.3.
I have reported the problem here.Is it a problem only happening in 3.5?
Hoping your reply.Thanks!
