I have gone through many documents and understand that Bluez5 removed the support to HFP profile. Inorder to work with HFP profile we need to make use of Ofono demon which will take care of registering the HFP profile with bluez demon and SCO connection. > > What my problem is very strange. > > I am using bluez5.14 and ofono1.14 demon which is running in my ubuntu mechine.Bluetooth Dongle is connected with ubuntu mechine.
