Warning #1: PX4/Pixhawk users upgrading from AC3.1.5 (or earlier) may need to re-do their compass and accelerometer calibration because AC3.2 also uses the backup compass and accels. Pre-arm checks have been added to ensure this has been done.
Warning #2: on the APM2.x the logs must be downloaded using MAVlink instead of the terminal.
AC3.2-rc14 is now available for BetaTesters through the mission planner’s Beta Firmwares link. The full release notes can be found in ReleaseNotes.txt and changes from -rc13 can be seen below.
Feel free to raise issues found during testing on this discussion or in the new support section in the APM Forum.
It’s a big release with “the onion” restructure and a bunch of new features (including these 57 closed items) so we need to re-test almost everything including all flight modes, all mission commands and all the new features. Marco and I will be maintaining (and adding to) this testing list. Issues reported will first be checked by Jonathan, Marco and I and then confirmed bugs/issues will be put on the github issues list (and then hopefully fixed).
Thanks especially to the beta testers who put their copters at risk testing each release. Enjoy!
Changes from 3.2-rc13
1) Safety Features:
a) fail to arm if second gyro calibration fails (can be disabled with ARMING_CHECK)
2) Bug fixes:
a) DCM-check to require one continuous second of bad heading before triggering LAND
b) I2C bug that could lead to Pixhawk freezing up if I2C bus is noisy
c) reset DCM and EKF gyro bias estimates after gyro calibration (DCM heading could drift after takeoff due to sudden change in gyro values)
d) use primary GPS for LED status (instead of always using first GPS)

Just to be sure: Is the M8Q compatible with APM and Pixhawk?
Thanks.

What GPS did you use before? How is it compare to LEA-6H?
fellow drone flyers, i want to update a correction here. i had reported about 15 days back the simonK based 20A afro ESC and BLHeli based sunrise 20A ESCs are having sync issues with Pixhawk loaded with AC3.2 firmware. I would like to post here that none of the ESCs had sync issue. The problem was with one motor of which i had no idea. i never thought that a motor can glitch without any apparent reason. the motor was turnigy 2830-980KV. they are wonderful motors. Out of the nine motors i bought only one was glitching and all this time i was busy changing the ESCs. after replacing the motor i had no issue at all while flying pixhawk with AC3.2-rc2 update. the motor could have magnetization problem (not sure). all modes are excellent. the navigation is superb. RTL always within 3m of takeoff. my apologies for posting wrong information.
Ravi,
Great, thanks for the correction!
Hi,
I would love if someone could give me an estimate time when the rc3 would be available?

I did seven WayPoint flight with 3.2 rc2 spline curve mission.The flight path was around the tree with single point of interest. Video is somewhat shaky because my gimbal mounting is to flexible. There is slight twitch when copter hit WayPoint but all in all good start.

tahines,
Looking good! Thanks for testing.
By the way, we've gotten rid of most of the twitches in Auto but spline is still not perfectly smooth as it goes through waypoints especially if the waypoint speed is high (like 10m/s). We know where the issue is (it's in the hand-over as it loads up the new waypoint) but we won't be able to completely fix it in AC3.2. In AC3.3 i'm sure we will be able to do completely twitchless highspeed spline tracks
tahines,
Cool, the twitches will be gone (i think) in -rc3.
By the way, the copter tuning looks a little squishy. AutoTuning on a Y6 can be a challenge but in any case, I think the tuning could be improved a bit.
Re the Dual GPS, I've corrected how it's used in the top part of this discussion. It seems it's not only logged but it also will pick the GPS with the higher satellite count. I think it only switches to the other GPS when it's satellite count is 2 higher than the currently used GPS but I'm still double checking that detail.
Hi Randy.
Would this include Piksi or just LEA or Neo series?
Regards
Henri
