This time I have a small How-To:<\/p>\n
Bring your Linux laptop online using your Treo 650 and GPRS (using Simyo as provider)<\/strong><\/p>\n What to do on the Treo 650: What to do on your Linux (Ubuntu) laptop: You should now have a serial connection between your laptop and your Treo.<\/p>\n Next we need to configure the scripts to dial in and hangup. In our example we use a German prepaid provider which has a quite cheap data plan, Simyo.<\/p>\n You create some files<\/p>\n 1. at 2. at and a file called Now you enter a One problem I had was the
\n<\/em> Switch on Bluetooth and enable “Netzwerk-Einwahl” (dial-up networking, DUN). Your might need firmware 1.12 on your Treo 650 to have this option in the Bluetooth preference panel.<\/p>\n
\n<\/em> Install the bluez-packets (bluez-utils). Next you use hcitool scan<\/code> to find your Treo and get its hardware address. The address looks like 00:07:E0:07:E6:A3<\/code> and is unique for any Bluetooth device. You can connect to the device using:<\/p>\nrfcomm connect \/dev\/rfcomm0 00:07:E0:07:E6:A3<\/code><\/p>\n\/etc\/ppp\/peers<\/code> a file called simyo<\/code><\/p>\n\/dev\/rfcomm0

After the connection was established, ifconfig<\/code> did show me the ppp0 connection and the assigned IP address, plog<\/code> told me also I was connected and even the Treo had the GPRS indication (2 green arrows on the signal reception gadget). I was using the ethernet connection (eth0) during the setup to look for help in the internet. After unplugging the network cable the laptop still had the old route (192.168.0.1) stored as default route. I had to manually enter route add default gw 10.121.30.0<\/code> to add a route to the new mobile connection.<\/p>\n
