Hi, Our drones reject commands after crashing / being moved. I would assume that this is because the sensors loose "calibration" and would crash if they where to fly. Thats obliviously good, but i would like to know when the drone enters this state so i can restart them. We have sys.canfly...

Thank you!

This did indeed fixed the navigation problem, but caused a new issue for us.
The drone flies as expected for 1-3 steps and then completely shuts down in air, reboots and freezes.

Manually flashing the drones isnt realistic for our use case.
We will have 10+ drones flying a show on stage and cant spend an hour reflashing all the drones if someone where to nudge the base stations.

Any idea when you guys will have time so solve this issue?

Thanks, We tried this today but without any luck. Just to make sure our code wasn't to blame i tested the CFlib "autonomous_sequence_high_level.py" with lighthouse basestation positions hard-coded in the lighthouse deck driver. Everything flew great and we experienced no issues, even with ...

Yeah the yaw offset video in the linked thread is identical to our issue.

We do have a bunch of testing that we'd like to get done in the near future, is #522 nearly solved or should we revert to an older commit?
If we need to revert, what commit do you recommend that we use?

Hey! So we flashed all our drones with the latest master at the time (5bcbb5e950b9c681c6d7ea8bbd228b9d33b54620) and everything worked fine for 2-3 sessions. Today when we setup the system our issues returned though. Our new (and likely old) problem seems to be related to the initial yaw position. Th...

Hello, We have been working with the Crazyflie Lighthouse positioning system for the last couple of months and these problems has been haunting us. There seems to be no real pattern to these failures, the takeoff->goto->land sequence works great sometimes, others fails miserably. We have 6 functioni...

Hey! Im using the Lighthouse positioning system and the Crazyflie mem "api" to access the basestation positioning. Firstly verifying that it matches my expected positions by reading and then writing if it doesn't. My program checks this every 5 seconds to make sure that we never fly on a m...

That was it, thank you!

Hey Recently upgrade a couple of my drones to the 2019.09 fw release. No modification was made except commenting out the "disable lighthouse" definition. Some of my drones (not all) have this weird issue where the lighthouse FPGA flashes as expected (blue, red, yellow) then goes completely...
