问题
I installed Bluez and I am trying to scan and get UUID Major, Minor and if possible mac address for nearby ibeacon. I found similar questions and they refer to a script which I found here . When I launch the script I get this error
Set scan parameters failed: Input/output error
Did someone know how to solve the problem or has another solution ? If I start transmitting with the beacon and then I start the scan I get no result at all and I have to interrupt the script.

You should test that the BlueZ installation is working properly on your Linux machine. Try using the hcitool dev command to see if it lists attached devices properly.
You may want to refer to a BlueZ installation guide like this one for Ubuntu to verify that you have your dongle set up properly.
