Description

Want to integrate eq3 thermostat and testing the connection. eq3cli --mac 00:1A:22:08:BF:D6

Scan was working, see the MAC address.

What I Did

Have placed the device about 2 meters from BT - USB stick, made scan, was working. (also tried bluetoothctl power off / bluetoothctl power on - with no changes in result)

The above exception was the direct cause of the following exception:

Any idea what can be the reason? (was working before with old Home Assistant installation at same Raspberry with same adapter - but software was updated)

Thanks!
