ERROR: Could not detect a CCLib_proxy connected on any serial port

[VladGavra]

Hello,

I'm trying to run cc_info.py for CC2531, but it seems on windows is not connecting to Arduino board (I'm using an Arduino Uno) and I get the following error: ERROR: Could not detect a CCLib_proxy connected on any serial port without any serial led blinks, and if I'm trying from Raspberry it gets stuck and I have to abort the script but in the beginning communicates for a second with Arduino board. Do you know a solution for this problem?

Thank you!
