Hello, I can't resolve following issue:

Hi, you can try switching the backend --backend [bleak|bluepy|gattlib] (remember to also install the other backends via pip). If you are running your script in a container, remember to mount dbus.

[wojtulab]

Actually dbus is mounted .

bash-5.1# ls /var/run/dbus
system_bus_socket

With bleak --backend bleak I have another error:

bash-5.1# eq3cli --mac='5C:E5:0C:B0:EF:88' --backend bleak

    raise BleakError(
bleak.exc.BleakError: Characteristic with UUID 1056 could not be found!

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

bash-5.1#

in bluetoothctl I can pair the device, current status:

[bluetooth]# info 5C:E5:0C:B0:EF:88

        Name: CC-RT-BLE
        Alias: CC-RT-BLE

        Trusted: yes
        Blocked: no
        Connected: no
        LegacyPairing: no

This behaviour is odd. Bleak is used by default, so the error messages shouldn't be different - not sure why this happens.

[wojtulab]

Ok what do i do? What do you suggest?

[wojtulab]

?

[TechHummel]

Sorry, not sure what to do here!
