Re: N900 tethered as *Bluetooth* modem - full solution?
 

I've had my N900 less than a week and I'm unbelievably impressed with it.

I've been trying to get the Bluetooth tethering working with Ubuntu using the instructions here, but it's giving me an error message after connecting to the phone, which states:
I've tried searching Google for the exact text and similar variations, but have come up empty-handed.
Can anyone give me any pointers? I'm happy to make changes using the terminal if someone provides step-by-step guidance.

FWIW, I'm on Vodafone UK and am typing this on the N900, so I know I have internet access enabled. The Bluetooth connection appears to be sound, as I've been using it for file transfer between the devices.

Not sure about that specific error, but I turned up this reference

Hope that's helpful...

Using what on Ubuntu? I just use the pon and poff commands as a font for pppd. I had to modify the chatscript from what worked with other phones, e.g. don't expect "CONNECT".

I'm seeing the same error message as insaleffe - but the connection is working!

The instructions I'm following are here:

After I see the error message, I just dismiss it, then (after a minute or so) click on the Network Manager icon up beside the time & date, and there is a new network for me to select under the Mobile Broadband category. I select it, disconnect my wireless connection and I'm good to go.
