Using a phone as a bluetooth modem among other things

Fairly soon here, I'm going to put a computer in my car (with Arch, of course) and use my 3G cell phone for internet.  How would I go about pairing the phone to my computer and how would I configure my phone as a modem?

Re: Using a phone as a bluetooth modem among other things

Oh, it's a LG CU-515 phone and I'm using a Broadcom bluetooth device.  I know the bluetooth on my laptop works, and I can see my phone with my laptop and vice versa.  Also, the phone supports tethering and a ton of other things ... it's not locked down from what I can tell, I checked that

bluez.org is where you need to go, it has everything you need. I don't know what our wiki has on bluetooth, but it would probably be worth a look too,

Re: Using a phone as a bluetooth modem among other things

bluez.org doesn't have any kind of comprehensive documentation at all from what I found.  And the "Bluetooth" entry in our wiki is very lacking too.  However, this morning, I searched for "bluez" in the wiki and found this one: http://wiki.archlinux.org/index.php/Blu … GPRS_Howto ... pretty much exactly what I was looking for

And now I'm in a hunch   Everything is going great, but when I run dsptool search DUN, it works for a few moments, then my phone says "Accept Bluetooth request from pwn ?"  Sweet, I say yes, and it saks me for pwn's pin.  I enter my pin, 45272, and the phone acts like nothing happened.  Then, back at the command line, I see ...

[root@pwn bluetooth]# sdptool search DUN
Inquiring ...
Failed to connect to SDP server on 00:E0:91:EB:1C:0C: Permission denied

Permission denied?  I gave it the right pin ...

Here's my hcid.conf:
