Hello,
We are experiencing issues with the Crazyradio, we are having a very short range of the radio link with the Crazyflie (both 2.0 and 2.1). When the drone is at a distance of about 1.5-2 meters from the Crazyradio, we are already having "low link quality" messages. There is a direct line of sight between the Crazyradio and the Crazyflie. This is weird because the store page says the range should be up to 1km.
We are controlling the drone with Crazyflie ROS.

Is there a way to fix this issue?
Thank you!

This is indeed not expected.

There is a couple of things I can think to
- Have you tried different Crazyradio to see if the problem comes from the Crazyradio or antenna.
- Are you setting up your radios with datarate/bandwidth of 2Mb
- Are you setting up big logging block? There might be a bug when using 32bytes packets that I am currently investigating. Limiting the size of the packets transmitted to the Crazyflie can help.
