\n
\nThese notes assume you have bluetooth already present and operational as was the case with my Ubuntu 7.10 system.
\n
\nInstall bluetooth support and confirm you can see your Bluetooth device.<\/strong>
\n
\n # hcitool dev
\n Devices:
\n hci0 00:02:5B:01:0D:CB
\n
\nConfirm you can see your TomTom<\/strong>
\n
\n # hcitool scan
\n Scanning …
\n 00:13:6C:9C:A0:5A TomTom ONE XL
\n
\nChange your bluetooth device’s class to report itself as a mobile phone offering Telephony services and confirm settings.<\/strong>
\n
\n # hciconfig hci0 class 0x500204 (I borrowed this class from my Nokia phone)
\n # hciconfig hci0 class
\n hci0: Type: USB
\n BD Address: 00:02:5B:01:0D:CB ACL MTU: 384:8 SCO MTU: 64:8
\n Class: 0x500204
\n Service Classes: Telephony
\n Device Class: Phone, Cellular
\n
\nTo have the device class retained as the default HCI configuration edit the file ‘\/etc\/bluetooth\/hcid.conf’<\/strong>
\n
\nWrite this file into ‘\/etc\/ppp\/tomtom.sh’ and ensure it has execute permissions.<\/strong>
\n
\n #!\/bin\/sh
\n \/usr\/sbin\/chat -e -f \/etc\/ppp\/tomtom.chat
\n
\nWrite this file into ‘\/etc\/ppp\/peers\/tomtom’<\/strong>
\n
\n noauth # Don’t require authentication
\n local # This is needed because it’s not a real serial line
\n noipdefault # Don’t use the local hostname to determine the local IP used
\n proxyarp # Proxy ARP connections
\n nodefaultroute # Don’t use the default route
\n noipx # Don’t use the IPX protocol
\n idle 0 # Set an unlimited disconnect timeout
\n
\n # Change the next three lines for your setup
\n
\n # :
\n #The first ip needs to be your computer, the second ip needs to be a non-used ip in your network
\n 192.168.10.204:192.168.10.214
\n
\n # ms-dns
\n # this needs to be a real dns server, look in \/etc\/resolv.conf
\n ms-dns 192.231.203.132
\n
\n # netmask
\n netmask 255.255.255.0
\n
\nWrite this file into ‘\/etc\/ppp\/tomtom.chat’<\/strong>
\n
\n ATZ OK
\n ATD CONNECT
\n
\nWrite\/Edit the file ‘\/etc\/bluetooth\/rfcomm.conf’<\/strong>
\n
\n #
\n # RFCOMM configuration file.
\n #
\n
\n rfcomm0 {
\n # Automatically bind the device at startup
\n bind no;
\n
\n # Bluetooth address of the device
\n # This is the address of my TomTom, put your own here!
\n device 00:13:6C:9C:A0:5A;
\n
\n # RFCOMM channel for the connection
\n # This is appears to be the channel used for DUN
\n channel 2;
\n
\n # Description of the connection
\n comment “Example Bluetooth device”;
\n }
\n
\nStart the Dial-Up Networking daemon. I found I needed to add the channel option.<\/strong>
\n
\n # dund –dialup –listen –channel 2 call tomtom connect \/etc\/ppp\/tomtom.sh
\n
\nRegister Dial-Up Networking service with bluetooth.<\/strong>
\n
\n # sdptool add dun
\n Dial-Up Networking service registered
\n
\nYou can use ‘# sdptool records local’ to see all local bluetooth services now registered.<\/strong>
\n
\nYou will need to add these commands to turn your PC into a router for the connection.<\/strong>
\n
\n echo 1 > \/proc\/sys\/net\/ipv4\/ip_forward
\n iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
\n
\nNow you are ready to connect with your TomTom, this is the tedious part as it has to be done manually.<\/strong>
\n
\nManage Phones -> Yes (search for phones) -> (select you linux machine) -> Continue -> Yes
\nSelect your phone model: -> Other
\nSelect your country: -> Other
\nDo you want to set up your wireless data connection manually? -> YES
\nAccess point name: -> OK
\nUsername: -> OK
\nPassword: -> OK
\nDo you want to obtain your IP address automatically (DHCP) or do you want to set up your IP address manually? -> Automatic
\nDo you want to obtain your DNS server address automatically or do you want to set up your DNS server address manually? -> Automatic
\nDial: -> OK
\nLogin script: -> OK
\n
\nYes to all ensuing prompts and you are done!!!!<\/strong>","protected":false},"excerpt":{"rendered":"
