bleak.exc.BleakError: Could not get GATT services: Unreachable

Hi, after connecting to my 16x16 display, attempting to change anything on the display results in these errors, with a connection icon flashing on the display.

Hi @Jesper117

this issue is related to the bluetooth library of python with the error message "bleak.exc.BleakError: Could not get GATT services: Unreachable". What display device do you have?
