Instructions For Ubuntu Desktop/Notebook Bluetooth Internet Setup - Please Click here
Note: For Ubuntu, we recommend to use the method for Raspberry Pi (via terminal/command-line) as described further below. The default graphical-interface method/screenshots in the above link had some random disconnect problems on a Ubuntu 12.04 computer/notebook we’ve tested with EcoDroidLink and also Bluetooth tethering from Android. After the annoying disconnect, the connection option in ‘network manager’ also disappeared list so it’s hard to re-connect - a re-pair and re-enable of the “Use mobile phone as network device” was required, but you can end up duplicate items in the network manager list. Therefore, we recommend to use the command-line method as described for Raspberry Pi below.
Since Bluetooth consumes less power than WIFI, Bluetooth Internet could be quite suitable for Raspberry Pi projects since it could help avoid USB power-supply limit issues (causing instabilities or strange behavior) when some USB WIFI or USB 3G Aircard dongles consume too much power/current/amperes from the Pi’s USB port.
For Raspberry Pi with Raspbian (and also recommended for Ubuntu on computers/laptops) please use the method below:
sudo apt-get install bluez-compat
sudo hciconfig -a hci0 up
sudo hcitool scan
Scanning ... 00:1A:7D:DA:71:0D EcoDroidLink
sudo pand -c 00:1A:7D:DA:71:0D -n
You can also try add the ‘–persist’ option as described here.
If it works correctly, it’d show output like:
pand: Bluetooth PAN daemon version 4.98 pand: Connecting to 00:1A:7D:DA:71:0D pand: bnep0 connected
sudo dhclient bnep0
DONE! Try ping www.google.com
To automate this, you can easily make a script containing the ‘pand’ and ‘dhclient’ commands above (with the bluetooth-address of your EcoDroidLink box) to connect and make it run/autostart on boot of your Pi.
Example output doing all the steps above:

This same method can be used for making your Pi or Ubuntu computer use internet shared from Android phones when ‘Bluetooth Tethering’ is enabled in the Android ‘Tethering and Hotspot’ Settings section.
Below is a screenshot of using internet on a Raspberry Pi (there is no Ethernet/LAN connected to the Pi - I’m using a Serial Cable to connect/login into the Pi from my Ubuntu computer via ‘GNU Screen’.)
Note: The ping might be a bit slower than normal just because the test was done in another room with a bathroom inbetween the room that the EcoDroidLink Access Point is working - this shows that the operation range and Bluetooth wireless penetration is quite good!
