Handy Tech Braille Star 40.

That makes sence. However, with Active Braille on bluetooth, this
doesn't happen at all. Another difference between these two devices
is that the Braille Star 40 is more slugish, e.g. it respnds slower
generally to key strokes on the display, compared to using Active Braille.

The display is not going into sleep state as it does when battery save
mode is enabled. I should also add that this delay issue was not present in
earlier versions of BRLTTY. unfortunately, I cannot remember exactly when it
was introduced.

Thanks and regards,
