Re: Flow deck issue

Your tests matches what I have experienced when running LPS and flow together: there is something that is sometime happening that makes the Crazyflie just 'snap' and crash. I suspect this comes from the EKF getting confused with conflicting information from both the flow and the LPS but I cannot be sure of it.
One thing to try could be to increase the standard deviation of the flow sensor (https://github.com/bitcraze/crazyflie-f ... .c#L94-L95) and/or of the down-facing ranging sensor (https://github.com/bitcraze/crazyflie-f ... .c#L47-L50). If the problem comes from conflicting data between LPS and Flow, increasing the flow standard deviation should help.
