And this is relevant on LKML because..? I don't think you will get the answers you need here, try the bluez-community or some ubuntu forum. In my experience, the ubuntu-crowd is quite responsive and helpful. > I have paired my mobile phone with ubuntu mechine.

Not sure > Why this is happening i am not sure i am doing any thing wrong. Again, how is this kernel-related? No please, don't answer. Just take my word for it. It's not. > But i am not seeing any communication between ofono and bluez , As a > result my mobile AG is not listed in the ofono modem list. > > Please help on this...... Have you tried google? > I have configured ofofno in /usr/ .... ./configure --enable-test ... then make ....make install Again, this is *not* kernel related. > Plese let me know why ofono not communication with bluez5 Probably because: - the configuration is messed up - you've done something wrong - the unicorns have stopped flying (only the purple ones, mind you) - you haven't dug into the problem enough. - you have a lot to learn, expressing queries in -any- search engine should be near the top of that list The fact that you have just highjacked a _completely_ random email from LKML show that you need to do more homework.
