Bitcraze Forums

Hello! We are using ZMQ to control the crazyflie and an external PID controller algorithm using optitrack was done. However, we're having problems with the connection of the crazyradio and crazyflie. Most of time the crazyradio disconnects automatically, and there are times that it has a hard time scanning for the crazyflie. We don't have any idea as to why it happens a lot since our current setup is inside a small room.

Hi,
Have you tried to change the radio channel used and to switch the radio datarate to 2Mbit/s?
