Copter-4.0.4-rc4 has just been released for beta testing and should appearing in the ground stations (MP, QGC) within the next few hours. Compared to the previous beta (4.0.4-rc3) this release includes the following bug fixes (Release Notes):
- Bug fixes:
a) Compass startup reordering based on compass priorities fix
b) TradHeli servo test fix
c) Precision landing logging fix
d) Mavlink commands ignored after reboot request
The first one is the most important and involves a problem we found with the new compass prioritisation code. In short we found that after the compasses were moved around in the MP’s fancy new compass prioritisation table, the COMPASS_DEVIDx parameters were not being re-ordered properly. This didn’t cause any troubles in flight but it was very confusing for support when trying to figure out which compasses parameters were being used for which device.
Surely this is the final beta so any testing is greatly appreciated!
