[BRLTTY] Bluez error in loop and no Bluetooth module

[André-Abush Clause]

Hi all,

On one my machine, logs are filled with this error:

This machine has no Bluetooth module. How to prevent this Error in loop?

I have tried to install the Bluez package (which makes absolutely no 
sense in my case), started the Bluetooth service. And I get another 
error in logs (in loop too):
