OS X Internet sharing with a P800

On the face of it, this shouldn't be a problem. After all, it apparently works on Windows.

My early efforts at this stemmed largely from this hint and this hint at MacOSXHints. However I was unable to get it to work. I was continually getting this error in my Console log:

Failed to open /dev/tty.Bluetooth-PDA-Sync: Device busy

but I cant for the life of me figure out what device is busy.

I then spent a few days fiddling with this method from TechnoHappyMeal, but after a lot of frustration I gave up on it. At the time I had decided that because my internet connection was coming through a USB port I wouldn't be able to share it over bluetooth (the various scripts that were developed in this and the MacOSXHints threads above all only specified built-in-ethernet or airport connections).

I left it for a while but then I heard about an app called Bluetooth to Internet Utility. It looked promising, but unfortunately it seems to have been broken by one of the recent OS X system updates. (In step 3 of installation it tries to open Sharing Preferences but instead opens Universal Access Preferences and then pops up an error window).

Then a few days ago I read about an app called P800 Manager which has an internet-over-bluetooth option. This app looks like it has (almost) cracked it. For one thing it can establish (and maintain indefinitely) a bluetooth connection with the phone (the phone's bluetooth icon shows a two-way connection, which none of my previous attempts had managed to do). Almost there! However when I fire up Opera on the phone it appears to manage to send out a page request, and I can see some data being downloaded over the broadband modem (courtesy of MenuMeters), but the data does not reach the phone. I'm not sure what is going wrong, but I am investigating the phone's settings and the Mac's port settings.

Update 9/12/04: I recently went wireless with an Airport Express which involved replacing my USB broadband modem with an ethernet one. This has solved my problem - P800 Manager's internet sharing works now! I still get occasional drop-outs of the bluetooth connection (which requires a restart of the P800 Manager sharing process), but I'm confident that is a P800 firmware problem fixable by getting a firmware upgrade.
