[BRLTTY] Bluez error in loop and no Bluetooth module

[André-Abush Clause]

Sorry, I should have thought of it... Thank you! That worked. :) I still 
have some errors when I {connect  a braille display}/{start BRLTTY}, but 
much less annoying. Such as:

op=0X5603: Input/output error

Tested with my two braille displays (Esys and VarioUltra).
