Hi Dave,
Thanks for this good advice! Yes I'm using a GUI (Ubuntu Budgie
desktop). I have now managed to get further.
I did some searching of the mailing list archives and found that the
reason I was getting the error messages about "braille driver
initialization failed" / "braille driver not found" was because I hadn't
installed libbluetooth-dev package before building brltty.
This is what I did to fix that:
# Uninstall brltty as root
sudo su -
cd /home/emma/repos/brltty
make uninstall
# Install libbluetooth-dev
apt-get install libbluetooth-dev
# Clean, rebuild and reinstall BRLTTY
make clean
./autogen
./configure
make install
After doing this, Bluetooth was working OK but I couldn't start xbrlapi.
I did some more mail archive searching and discovered that I needed to
make sure /etc/brlapi.key is world-readable (mine wasn't, it was
read-write for owner and no permissions for group or others).
chmod ugo+r /etc/brlapi.key
Then I could start up brltty and xbrlapi OK:
# In one console run brltty in the foreground
sudo brltty -n -e -ldebug -b bm -d bluetooth:5C:B6:CC:86:F3:75 -L
/tmp/brltty-bluetooth.log
# In another console window as my personal user (not root), run xbrlapi
in quiet mode in the foreground
xbrlapi --quiet
After doing this I can type lower case letters OK with my Orbit Writer
keyboard which is progress.
Looks like the Orbit key bindings are getting picked up OK

BRLTTY is initially configured to use US Computer Braille for keyboard input
https://brltty.app/doc/Manual-BRLTTY/English/BRLTTY-6.html
https://brltty.app/doc/Manual-BRLTTY/English/BRLTTY-14.html
I can type upper case letters by adding dot 7 to the lower case letter.
But when I try to type anything else in Computer Braille for example the
at sign, which is supposed to be dots 4 and 7, or Computer Braille
numbers, I don't get the output I expected. For example dots 4 and 7
produces an AE symbol.
I've tried these options (and also tried with Orca on or off) but they
don't alter the output:
set braille typing mode text: Space+Dots467
set contracted/computer braille: Space+Dots1245
Log attached of me typing in US Computer Braille
hello @
The output I actually get is
hello Æ
Help much appreciated,
Cheers!
Emma
