Hi,
I am trying to connect my Ubuntu laptop to the On Board Diagnostics in
my car using a $35 bluetooth adapter. I have been following a nice
guide for doing this on an Andriod Phone [1]. From Ubuntu I can
detect the ODB2 bluetooth adapter, get the MAC address, and create a
serial device for it (/dev/rfcomm0). When I run minicom I get
prompted for the blutooth PIN, and then minicom fails to open the
device. I am not even sure if the pin number authentication
succeeds...
The device file /dev/rfcomm0 exists, and when minicom tried to open it
I see bluetooth traffic using hcidump.
Has anyone else done this or something similar ?
$ sudo -i
$ hcitool scan
Scanning ...
00:0D:18:B1:11:42 CBT
$ rfcomm bind 0 00:0D:18:B1:11:42 1
$ minicom
<prompted for password at this point - gui dialog box>
minicom: cannot open /dev/rfcomm0: No such file or directory
( I have the corresponding hcidump output posted on Pastebin [2] )
