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)

@Christian, @Thomas, I had just bought a new uBlox M8N GPS receiver. i understand that baud rate and SPI has to be changed before i connect it. can u pls share how to change these settings on new M8N GPS before connecting to Pixhawk GPS port. is there a utility for changing the GPS settings. i think baud rate has to be 38400
uBlox has free software for testing and setting up of gps modules. You will need an FTDI cable.

Hi Randy,
I noticed in the Datalogs produced by v3.2(rcX) has dropped the FMT line for "MOT" (for motors). Was there a reason behind this? It was very useful for detecting how many motors were attached even when no logging was taking place for the motors.
For example, from v3.1: FMT, 11, 11, MOT, hhhh, Mot1,Mot2,Mot3,Mot4 = 4 Motors, or FMT, 11, 19, MOT, hhhhhhhh, Mot1,Mot2,Mot3,Mot4,Mot5,Mot6,Mot7,Mot8 = 8 motors.
Is there another way of detecting the number of motors in the datalogs?
Cheers
Kev
Kev,
The info is all still there but it's been renamed from MOT to RCOU (i.e. RC Out) to make it consistent with Plane.
AC3.2-rc14 is now available through the mission planner's Beta Firmwares link. Changes can be found in the ReleaseNotes.txt but I've also added them in the main section of this discussion (see above).
I really hope and expect this to become the official AC3.2 release. So we will leave this in the BetaFirmwares area for the next week or so and if nothing too bad turns up we will rename it to AC3.2 (around Nov 7th) and then ask the wider community to start loading it (still from the BetaFirmwares link) and then two weeks after that (i.e Nov 21st) we will replace AC3.1.5 with AC3.2 as the default version distributed by the Mission Planner and APM Planner2.
As always thanks very much to all of you who help us with the beta testing.
No.... Thank YOU!
thank you so much randy!
Daniel,
I suspect the GPS on your vehicle is outputting NMEA which we've had to drop support for in AC3.2 (on the APM2.x) because we're out of flash space. If you're using a UBLOX then it seems like the GPS isn't configured correctly to output UBLOX binary messages. That's a bit unusual because on startup the APM tries to set the config of the GPS so that it output Ublox Binary instead of NMEA. There are instructions on the wiki as to how to configure the Ublox GPS.
I see the release notes for a few days have shown that there is an rc14, however mission planner has not picked it up yet.
Is rc14 on hold?
I´m also trying through mission planner but I still get RC13. Let´s hope it comes out before the weekend!
