This page describes how to configure PPP dialup through a Bluetooth-compatible mobile phone. The emphasis is on using GPRS/EDGE services. These instruction were compiled and tested on the Dapper Drake development release.

Configure mobile phone data profiles

Getting the data access profile

T-Mobile

T-Mobile accounts generally require separate data profiles for WAP and general data access. (Some people have had success running a regular data connection over the WAP profile.) Getting access to general data access requires a data access plan. Currently, the "Unlimited Internet VPN" is the best deal, as it costs the same as the "Unlimited Internet" plan but gives you a real, public IP address. Incoming connections are blocked on any T-Mobile data plan. T-Mobile does not seem to offer metered data plans anymore.

There are two ways to get the data service profile on your phone.

Automatic

T-Mobile can send the data services profile directly to your phone via SMS. Only the "wireless data" customer service people can send the data services profile to your phone. The regular service people can only send the WAP data profile, which will not work for general use. You will have to be transferred once or twice to reach the wireless data division. Once there, simply request that the data service profile for your plan be sent to your phone. (Of course, you'll need to be signed up for a data plan.)

Once you receive the plan information, your phone will ask you where you want to store it. T-Mobile uses profile 1 for the WAP profile, so don't overwrite it. I recommend using profile 2, as it's usually the first empty profile.

After storing the data services profile, your phone will probably set it as the default. This will probably cause your WAP (T-Zones/T-Mobile Internet) to fail for your on-phone browser. Set the WAP data profile (profile 1) to default fix this. See the configuration section below for your phone's brand. Setting the default profile is usually fairly obvious once you've reach the data services configuration screen.

Manual

Access the data profiles configuration for your phone's brand using the instructions under the configuration section below. The order and name for settings is for a Samsung T809. These settings are verbatim from the SMS T-Mobile sends Unlimited Internet VPN plan users.

Use the following settings for the Unlimited Internet VPN plan:

• Name: T-Mobile VPN

• Home URL: http://www.t-mobile.com

• Bearer: GPRS only

• Proxy use: Disable

• GPRS settings

  • DNS1: 0.0.0.0

  • DNS2: 0.0.0.0

  • APN: internet3.voicestream.com

  • Login ID: Empty

  • Password: Empty

Other companies

Call your mobile service provider and request information about data plans. Many charge by the megabyte, but unlimited plans are increasingly available. Most of the instruction for T-Mobile will probably apply.

Configuration

Sony Ericsson GSM

This is from my memory of using a T610, but it should apply to any Sony Ericsson phone. Choose the lower-left icon from the main menu.

Samsung GSM

This is tested on a T809, but should apply to any Samsung GSM phone. Enter code *#87927# from the main screen. Select "Current profile" to choose the default profile. Select "Profile settings" to manage profiles.

Installing Bluetooth packages

Run the following at a shell prompt:

sudo apt-get install bluez-utils bluez-pin pppconfig

Listing Bluetooth devices

• Make your phone Bluetooth discoverable.
• Run the following at a shell prompt:

hcitool scan

• Copy the MAC address (the text with the capital letters, numbers, and ':'s) somewhere convenient. You'll need it many times.

Pairing

• Run

sudo nano /etc/bluetooth/hcid.conf

• Modify the pin_helper setting from /usr/bin/pinwrapper to /usr/bin/bluez-pin

• Run

sudo /etc/init.d/bluetooth restart

• Run the following, replacing your-phone-mac-address with the proper data

hcitool cc your-phone-mac-address

• Run the following, replacing your-phone-mac-address with the proper data

hcitool auth your-phone-mac-address

• Accept the pairing from your phone handset

Configuring the rfcomm device

Configuring PPP

Authorizing dialout

Run the following at a shell prompt, replacing your-username-here with your username:

sudo adduser your-username-here dialout
