Alfred firmwares

[AlexanderG]

Hello,

For interested users, we will provide 'Beta' firmwares, so you can try out updated Sunray versions for your Alfred (so, before we make a Beta version an official release). There is not guarantee that Beta versions will work. You can always go back to the lastest release version by clicking on 'Firmware->Apply update' in the Sunray App.

To apply a beta version, copy the beta version URL below, enter it in the Sunray App firmware menu and click on 'Custom update' in the Sunray App.

[AlexanderG]

Version 1.0.302: mower motor bugfix (mowing motor not starting)
Version 1.0.303: I2C bugfix (sporadic firmware crashes)

 

[AlexanderG]

Version 1.0.305: improved dock touch recovery (robot will slightly move if charging contacts are bad)

 

[AlexanderG]

Version 1.0.307: timetable - see Sunray manual for details

 

[AlexanderG]

Version 1.0.310: more robust (RTK-based) course estimation. Robot will ignore RTK-point (for 2-point course estimation) if there was an IMU rotation while measuring this RTK point. As a consequence of this improved sensor evaluation, the line tracking controller (Stanley) will work better. If your robot sometimes mows larger curves instead of straight lines, this update should bugfix it.

 

[AlexanderG]

Version 1.0.312: less sensitive rain sensor, forward driving after undock, turned-off 'kidnap-recovery' near dock

 

[AlexanderG]

Version 1.0.314: lift sensor bugfix (robot will continue mowing if lift sensor was activated at some obstacle)

 

[AlexanderG]

Version 1.0.315: bugfix robot 'no-gps-motion' (obstacle error) while rotating after undocking
