I haven't looked at it in a while, but when I was getting the Xoom working, I noticed the initial script looked like it might have gotten the dbus-send command to prompt for the internet connection truncated. I don't use it, so I forgot to follow up on that (sorry 9k).

In terms of getting a bluetooth symbol but not the tethering symbol showing: when you pair the n900, are you seeing tethering on the Xoom's n900 bluetooth profile? If so, you might be running into the same problem I *think* I did. I did this all in somewhat of a hurry, but I believe the fix was to make sure the n900 was setting the Xoom's dns values in the dnsmasq run settings. See the script I posted a while ago for the commands and just try adding the dns values to the end of 9000's dnsmasq run command.

Playing around with it again & got it to work!

Not doing anything special but it seem very particular in how it starts up.

1. Devices are paired but have to be connected too.
2. Then run that bluetooth-pan-tethering.sh script
3. Now it should be tethered for internet. Doesn't look like you have to be connected to the net on the n900 first for it to work either. Did it as a last step & it worked.

Now if there were a way to have the tablet just activate the net connection on the n900 when it needs it & a way to connect them w/o having to manually activate that script every time or at least a shortcut for it.

Hopefully it'll work the same on the Samsung Tab 10.1 that's gonna replace this Transformer tomorrow.

Glad to see it works for another tablet. Samsung Tab 10.1 should work too as it is running honeycomb.

Re: [HOWTO] N900 Bluetooth-PAN Tethering (N900 supplies Internet Access for PC)

hi,

@9000
i tried your howto to share my n900 connection with my eeepad transformer (android honeycomb), but it doesn't work.

could you help me to debug ?

i followed the howto, and the script didn't reported any errors into the terminal.

i installed kernel power for user v47, iptables and pc connectivity manager from extras-devel pr1-3.

i don't know what to do with the options in pc-connectivity-manager...

@youth
i saw in the pic bluetooth tethered, i don't have this on mine !
have you done something special to get this message ?

thanks for helping me
ps:sorry for my english

Re: [HOWTO] N900 Bluetooth-PAN Tethering (N900 supplies Internet Access for PC)

The tablet was already paired with the phone & I then connected them. After that ran the script bluetooth-pan-tethering.sh & that symbol came up. Then made sure the phone had a net connection.

That said I just got a different tablet the Samsung Tab 10.1 & I'm having trouble establishing that "Bluetooth Tethered" connection reliably. I hope it's not a hardware issue though it is working right now as I type this message.

For diagnosis please give me the output of the following in N900 after you pairing them up and triggered the script:

Code:

root

ifconfig bnep0

route

ps ax | grep dnsmasq

Re: [HOWTO] N900 Bluetooth-PAN Tethering (N900 supplies Internet Access for PC)

actually, i'm downgrading kernel-power on v46 and i will give some feedback.
thx

I know it's not comparable but i try bluetooth tethering with an android phone (2.2) with the asus eeepad and everything works fine.

@Cowboy everything seems fine. Are u sure there is no error during execution? Can you show us the output?
