I would like to use my Android phone (Samsung GT-I8190) or Android tablet
(Nexus 7) as a Bluetooth connected terminal for my BBB, but I'm having
trouble figuring out how to do so.
It seems I have got the Bluetooth adapter running OK on the BBB since my
Android devices can discover a 'beaglebone-0'. I can also l2ping them from
the BBB
as you can see below from a BBB Putty session log taken on my laptop -
although the Nexus 7 apparently returns a ping packet of 0 bytes:

When I try to connect to the BBB via the Bluetooth Terminal Emulator Pro
app on my Androids, I end up with 'unable to connect device'
I figure there must be a bunch of settings I have to make in the BBB Linux
config files to make things work as I want, but I have Googled far and wide
in the search for answers and can't seem to find all the peieces of the
jigsaw.

Suggestions gratefully received.
