Using Varioultra With Linux - Baum VarioUltra 20 User Manual

Let's say that your iPhone is connected on Bluetooth channel 3, but you
want it to be on Bluetooth channel 1. It's easy to change it. For example:
a new device is connected to Bluetooth channel 3 (BT3) and you want to
assign it to Bluetooth channel 1 (BT1). To change it, follow these short
instructions:
Press S2 + B6. VarioUltra shows the channel and the device name.
While the hint message is shown, press B4 for about a second and
release. VarioUltra assigns the device to Bluetooth channel 1 (BT1).
Note: If BT1 was holding another device, that device is automatically
assigned to BT3. In other words, the channels are swapped.

2.8 Using VarioUltra with Linux

Our thanks to VarioUltra user Scott McCormack for his contributions to
this section.
The assumption is you are somewhat familiar with using Linux, and that
you're comfortable working from the command line.
REQUIREMENTS:
Braille support under Linux is provided by an application called BRLTTY.
Most Linux distributions come with a version of BRLTTY. However, since
VarioUltra support was only added in version 5.3 and most distributions
come with older versions, it will be necessary to install an updated
version of BRLTTY to get VarioUltra to work. For the purposes of this
instruction, we are using Ubuntu 14.04, which comes with BRLTTY 5.0.
Even the newest Ubuntu 15.10 only comes with 5.2. Most people are
probably running older versions of BRLTTY.
Confirming your BRLTTY version. From the command line type:
brltty -V
Note the capital V. This will print out the version number of BRLTTY
along with some other information, and then return you to the command
line. If you get 'brltty: command not found' you don't have BRLTTY
installed at all. This means you can proceed to the download and install
steps.
Remove Old Versions. If your distribution came with BRLTTY installed
and it isn't version 5.3 or later, you should remove it before installing a
new copy. To do this, you will need to use the package management
tools included with your distribution to remove the existing copy of
