GPRS INTERNET ACCESS with LINUX COMPUTER via BLUETOOTH-CONNECTED MOTOROLA RAZRv3 PHONE
rm 21.-23.Nov.2005

using:
- Motorola RAZR v3 / ONE.at
- Linux SUSE 10.0
- (Belkin) Bluetooth USB Adapter - most brands and models will do fine

1. USAGE ==================================
1.1. Bluetooth (remember to use your own Bluetooth address
                     instead of 00:15:09:AB:CD:EF
                         - see section 2.2. in Installation below)
1.1.1. Hardware
 (- power on Bluetooth in the phone if it was off - I have it always on)
  - insert Bluetooth USB Adapter - then:
  - in first rootshell:
1.1.2. Bluetooth connection between computer and phone:
  # rfcomm connect /dev/rfcomm0 00:15:09:AB:CD:EF
  
  there must be no errors - (there should be the message
   to type Ctrl-C to close the connection)

1.2. GPRS connection between computer and internet provider via phone:
  in second rootshell:
  # pppd rfcomm0 call gprs-script

  (you should see a long modem dialog sequence, near the end 
   there should be shown your new local IP address and the
   hint "type Ctrl-C to terminate" or similar)

1.3. ... use Internet ...
  - for a quick test you can type 
    > ping artm-friends.at 
    or your favorite ping host

1.4. Shutting off:
  - terminate pppd by typing Ctrl-C in the second rootshell
  - terminate bluetooth by typing Ctrl-C in the first rootshell
  - pull off Bluetooth USB Adapter

2. INSTALLATION ===========================
2.1. script files:
create this file and save as /etc/ppp/peers/gprs-script:

115200
debug
connect '/usr/sbin/chat -f /etc/ppp/chat-gprs-v3 -r /dev/console'
crtscts
noipdefault
modem
usepeerdns
defaultroute
connect-delay 5000

(end of gprs-script)

create this file and save as /etc/ppp/chat-gprs-v3:
(remember to adapt your GPRS APN in the but last line, here "web.one.at")

TIMEOUT         5
ECHO            ON
ABORT           '\nBUSY\r'
ABORT           '\nERROR\r'
ABORT           '\nNO ANSWER\r'
ABORT           '\nNO CARRIER\r'
ABORT           '\nNO DIALTONE\r'
ABORT           '\nRINGING\r\n\r\nRINGING\r'
''              \rAT
TIMEOUT         12
OK              ATE1
OK              'AT+cgdcont=1,"IP","web.one.at"'
OK              ATD*99***1#

(end-of chat-gprs-v3)

2.2. Bluetooth preparations: 
- insert the Bluetooth USB adapter, close a KDE Bluetooth dialog if one pops up
- in the Motorola phone switch Bluetooth on 
       and make it visible ("Find me" in the Bluetooth menu)
- find out the Bluetooth address of your phone using the Linux command:
  # hcitool scan
I got 00:15:A8:xx:xx:xx for my phone - replace your phone address everywhere 
in this file!
I use 00:15:09:AB:CD:EF here as an example.
Then fiddle with YaST to get pairing working - this is a problem because KDE seems 
to mix in and because the Motorola can not initiate a pairing sequence like other 
phones can so you must initiate the pairing from Linux. This only works if the 
settings in YaST are correct, I now have the following:
- Bluetooth services activated
- Security Manager 
   - use local PIN (enter your favorite 4 or 5 Digit PIN number)
   - on the Security Options dialog box
         - Authentication: ON
         - Encryption: OFF
         - Inquiry Scan ON
         - Page Scan ON
note that these are the default settings IMHO, but they worked for me 
only after I changed them and later changed them back to what they were 
in the first place!

2.3. Bluetooth device pairing:
- in a rootshell type:
  # rfcomm bind /dev/rfcomm0 00:15:09:AB:CD:EF 1  
                 #or: rfcomm bind /dev/rfcomm0 0 00:15:09:AB:CD:EF 1
                 #if errors occur release the dev with: rfcomm release /dev/rfcomm0
                 # try to change Bluetooth settings in YaST...
                 #then issue the bind command again... 
                 # until binding is successful ]
Pairing will be stored permanently in the Linux system, so you have to do this only once.
