So, I finally got Internet access over Bluetooth to my Nokia 6233
working. Here's a short summary of the steps taken (this assumes
a properly configured phone).
Make sure your Bluetooth device is recognized by OpenBSD:
$ dmesg | grep ubt
ubt0 at uhub4 port 1 "Micro Star International Bluetooth" \
rev 2.00/32.64 addr 2
Install the bluetooth-tools package. This provides, among
other things, btconfig, btpin and rfcomm_sppd.
Bring the Bluetooth interface up and verify that you're able
to detect your phone:
$ sudo btconfig ubt0 up
bthub0 at ubt0 00:21:85:b2:51:41
$ btconfig ubt0 inquiry
Device Discovery from device: ubt0 .... 1 response
1: bdaddr 00:1d:e9:e5:ad:01 (phone)
: name "Nokia 6233"
: class: [0x5a0204] Cellular Phone <Networking> <Capturing> <Object
Transfer>
<Telephony>
: page scan rep mode 0x01
: clock offset 27997
Add the bdaddr to /etc/bluetooth/hosts so you don't have to
type in the address each time you want to refer to your phone:
$ sudo echo "00:1d:e9:e5:ad:01 phone" >> /etc/bluetooth/hosts
Start bthcid(8), generate a pin using btpin(1) and connect to
your phones' Dial Up Networking (DUN) service using rfcomm_sppd(1).
$ sudo /usr/local/sbin/bthcid
$ btpin -a phone -r -l 4
PIN: 2701
$ rfcomm_sppd -d ubt0 -a phone -s DUN
You should receive a question on your phone if you want to accept
the connection and then type in the PIN generated above. You
should now be able to communicate with your phone:
rfcomm_sppd[16519]: Starting on stdio...
AT
OK
ATI3
Nokia 6233
OK
Now that we know this works, we can attach this to a pty:
$ rfcomm_sppd -d ubt0 -a phone -s DUN -t /dev/ttyp0
$
Create a ppp interface and connect using pppd(8) [1]
$ sudo ifconfig ppp0 create
$ pppd call netcom
$ ifconfig ppp0
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
priority: 0
groups: ppp
inet 89.8.5.99 --> 10.6.6.6 netmask 0xff000000
(fancy IP address ;-)). Now check the routing table:
$ netstat -rnf inet | grep default
default 10.6.6.6 UG 0 0 - 56 ppp0
I've no idea what the name servers are supposed to be, so I
just started a local one and pointed /etc/resolv.conf at it;
$ sudo /usr/sbin/named
$ sudo echo "nameserver 127.0.0.1" >> /etc/resolv.conf
We're on!
