[BRLTTY] Bluetooth with Brailliant display (Baum)

[Daniel Dalton]

Hi, 

I'm using a Humanware Brailliant, wich is manufactured by Baum, however,
I'm not sure what the corresponding model name is... 

I'm attempting to establish a bluetooth connection between the
device. I've created a pincodes file in
/var/lib/bluetooth/bluetooth_address/pincodes 
I've also edited brltty.conf and put the bluetooth address in on the
braille-device bluetooth device specification line. 

When starting brltty I get this error in syslog:
Oct 10 15:34:53 debian-laptop bluetoothd[4557]: Adapter

Oct 10 15:35:01 debian-laptop brltty[4349]: RFCOMM connect error 4:

Here is my setup configuration:

daniel at debian-laptop:~$ sudo hciconfig hci0
hci0:	Type: BR/EDR  Bus: USB
	BD Address: 94:39:E5:D5:B7:86  ACL MTU: 1021:8  SCO MTU: 64:1
<snip> 

cat "/var/lib/bluetooth/94:39:E5:D5:B7:86/pincodes"
94:39:E5:D5:B7:86 1234

daniel at debian-laptop:~$ grep bluetooth /etc/brltty.conf|grep "braille-device"
braille-device	bluetooth:00:17:91:02:05:4B

I'm told by humanware the code 1234 is be correct, I tried other
codes such as 1111 0000 and got the same error. 

Thanks for any help. 

Cheers,
Dan
