WARNING: numerous reports of telemetry connection issues have been reported with this release. -rc3 will be released within the next 48 hrs with a fix so we recommend waiting for -rc3
Rover-4.1.0-rc2 has been released for beta testing and can be downloaded from the ground stations (MP, QGC) using their beta firmware links.
The changes vs -rc1 are in the release notes and copied below
Changes from 4.1.0-rc1
a) Log download speeds improved on F765 and F777 based boards (USB buffers increased)
b) Serial port DMA contention heuristics improved (reduces chance of delays writing to serial devices)
- Bug Fixes
a) CRSF frame timeout increased to reduce RC failsafes
b) Declination automatic lookup rounding fix (caused inaccurate declination in some parts of world)
c) DShot (bi-directional) support on Pixhawk4, CUAVv5, CUAVv5-Nano
d) IMU semaphore fix to avoid occasional corruption
e) QioTek Zealot F427 GPIO pin fix
f) Replay/DAL RMGH log message format fix
g) Rangefinder initial buffer size and baudrate fix (affected Aintein US-D1 radar)
Let me just say I’m sorry for pushing out yet another release candidate when I think we are all satisfied that Rover-4.1.0 is “fully baked” and ready to become the stable version… the only reason I did this is because it saves administration time if I keep the Rover and Copter releases in sync and an official release requires a bit more time than I had available today.
The changes are all relatively minor and are in areas shared with the other vehicles so we can trust the Copter and Plane beta testers to test these for us.
… so assuming nothing unexpected happens I’ll release this version as Rover-4.1.0 stable within a week. If anyone puts it on a vehicle and gives feedback that is greatly appreciated but no huge pressure.
Thanks again to all who have beta tested Rover-4.1.0!
