Need help in Bluetooth reverse tethering

[vijay Badawadagi]

Hi,

We are able to get Bluetooth tether on ICS in NAP role, things like connecting PC to the tethered device and browse, but the reverse is not working. BT enabled device in PANU role is not working, i cannot browse from mobile phone by connecting it to another phone which is NAP. I always get the internet connection not found, I did ensure that when the connection is established the option to use the device internet is enabled for the NAP role device.


The changes needed for the
framework/base/core/res/res/values/config.xml are in place because of which NAP role is functional.

Any pointers to get PANU role functional from phone.

Thanks
Vijay

Well surprising that even after matching the init.rc and the
config.xml entries to that of the samsung galaxy nexus on ice cream
sandwich we seem to be missing something to get the reverse tethering
working ....

anything else we should be looking at ?

Matthew, We got it working.
However, we had 2 development platforms - 1 with no modem and another
with modem and data interface rmnetX up and running.

We are trying to figure out what needs to be done to get reverse
tethering working on NO modem platform since via the modem platform
when the data connection is removed we do see the BT tethering working
fine...

It would help us to know the basic building blocks ?? As of now we
know of upstream interface configuration as bnep0 and that's about it
...
Anything specific required to kick start ConnectivityService ? etc... ?

The routing part is handled by Connectivity Service. Look at BluetoothTetheringDataTracker.java which calls into Connectivity Service for reverse tethering.

Yes in our case, messages were not being propagated to connectivity service from Bluetooth Data tracker.


Thanks every one for the help

Hi,

Do you make Bluetooth reverse tethering working fine?
My phone has similar problem;

"messages were not being propagated to connectivity service
from Bluetooth Data tracker."

There is a java exception, and it make the android reboot.
I think the handler is not valid!
