Thank you for your answer. I think I get it.

Hi,
I also observed sudden physical crash while the Crazyflie moving slowly. I was confused about this.And when I repaired it and it can also perform well. I couldn't dope out any solution about this problem.

Hi, I have changed NRF_FLOW_CTRL pin(nrf51822 is P0_14 pin and stm32F4 is PA4) to new connection(nrf51822 is P0_08 pin and stm32F4 is PC15) in my own PCB. I also changed the pin init of NRF_FLOW_CTRL in stm32 and NRF firmware. I think is ok but the pulse of NRF_FLOW_CTRL pin when connected to the cl...

Thank you for your help.I observed a real physical crash.I setup my system in a rectangle and fly inside the convex hull. I think it can be my quadcopters' physical problem. Now I try to repair them.Do you have some suggestion to test a quadcopter is enough stable to fly ? It often performed very we...

Thank you for your answer. I have try the latest master branch of the firmware but it also happened when I control to flight in a circle.Maybe my Quadcopters are not stable enough or the position estimation of kalman filter isn't faster enough to run a quickly circle.

Hi! Thank you for your answer.I have traced the Quadcopter and get the position from the python script, the data is right which close to setposition. But I measured the height is inconsistent so much.I find this inconsistent when I using TDOA and TWR , and I find the inconsistent of height is larger...

Hi ,I find the latest version TDOA2 will often appear sudden impact crash, I'm not sure whether it is my Quadcopters' problem or others, but I have test 10 Quadcopters and found crash more easily than TWR, I don't know what cause it ? Maybe the firmware have influence on it ? can you give me some he...
