Synchronization with the autopilot fails #61

Open Chris-Bee opened 8 years ago

Chris-Bee commented 8 years ago

Hello,

we encountered an issue with the time synchronization between the host and the asctec autopilot platform. The warning of the offset time shows a constantly increasing value. Each step increases the offset by 1ms. So it makes it worse instead of getting closer to the sync state.

Is this a known issue or das someone know any reasons for that?

Hello, has there been any changes regarding the synchronization issue? If the time difference between client and server is too high, the synchronisation steps seem quite random and do not converge even for hours:

imu time is off by 13107.5
imu time is off by 10682.6
imu time is off by 7012.61
imu time is off by -130.816
imu time is off by -2883.33
imu time is off by -4062.98
imu time is off by -3735.3
imu time is off by -1965.82
imu time is off by 655.616
imu time is off by 393.472
imu time is off by 3735.81
