Installing oFono should generally be fine assuming it was compiled with --enable-bluetooth. In a similar way, BlueZ should be compiled with --with-telephony=ofono. If it doesn't work, make sure your BlueZ audio.conf includes Enable=Gateway. This might be necessary depending on the exact BlueZ version you're using (e.g. some distros have patches to enable this profile/role by default). Cheers, Mikel
