10 years ago This issue is strange. Now I have discovered that without changing anything, sometimes the cfclient connects to the crazyflie without problems and sometimes it gives this error. I can not say what is happening.

After updating to the last mercurial version (1b45d73) the cfclient on Linux can not connect to the crazyflie. The connections was working fine until the last update. No other changes made to the system.
Linux debian unstable Python 2.7.6 Crazyflie 10-DOF

Until the line "INFO:cfclient.ui.tabs.FlightTab:Clientside X-mode enabled: True" it is the cfclient startup. I press Connect and select the crazyflie. Then I get this error.
