Copter-3.5.0-rc2 (2nd release candidate) is now available for beta testing. As per usual the beta version can be downloaded using the MP's Install Screen's beta firmwares link and I believe there's a similar ability in QGroundControl.
There have been quite a few changes and fixes compared to the previous release candidate. Most of these changes are listed below or can be seen in the ReleaseNotes.txt.
Changes from 3.5-rc1:
- Improved dual GPS support including blending (set GPS_TYPE2=1, GPS_AUTO_SWITCH=2)
- AutoTune with position hold (enter AutoTune from Loiter or PosHold modes to enable light position hold)
- New boards/drivers:
a) PixhawkMini support
b) AUAV2.1 board support (for AUAV2.1 set BRD_TYPE to 20 to distinguish from PixhawkMini)
c) Garmin LidarLiteV3 support
d) Maxell Smart Battery support
e) Invensense ICM-20602 IMU and ST L3GD20H gyro drivers added- IMU to Motor lag reduced by 0.6ms
- Object Avoidance:
a) support TeraRanger Tower sensor
b) support using normal (1-dimensional) lidar/sonar- Minor changes/enhancements:
a) add MOT_SPOOL_TIME parameter to allow users to control spool-up time of motors
b) remove Solo gimbal from -v2 because of 1MB Flash limit on many Pixhawk1s (Solo users should use -v3 firmware)
c) altitude check for Guided mode takeoff (must be at least 1m)
d) auxiliary switch to arm/disarm vehicle (set CH7_OPT to 41)
e) change battery alarm tone to reduce impact on IMU
f) add battery monitor health reporting
g) support DO-FENCE-ENABLE mission command to enable/disable fence during missions- Bug Fixes:
a) OLED Display clears messages after 10seconds
b) Servo Gimbal output range fix (could attempt to push servos beyond their limits)
c) fix do-set-servo
d) fix dataflash log time (was always appearing as 1970)I suspect this release is quite close to the final official version but there will be at least one more release candidate. We hope/expect to pick up the pace of release candidates from now on - releasing one new release candidate each week or so until we get to the final version. I.e. only bug fixes from now on.
Thanks very much to our beta testers for helping us find issues before the official release!
