在Bluez中创建dbus接口

Question

A question regarding the creation of dbus interfaces such as

org.bluez.Audio, org.bluez.AudioSource

appearing on d-feet debugger.

Does the host running Bluez(For eg. Laptop) create an interface org.bluez.AudioSource for a remote device behaving as a Bluetooth A2DP source?

So similarly how to create an org.bluez.AudioSink interface on any bluetooth phone for example to make it behave as an A2DP receiver? In that case should the host(for eg. Laptop) create an AudioSink interface for interacting with the bluez on the phone side?

Answer 1

in C to create A2DP connection u can use these parameters

DBusMessage *msg;   
msg = dbus_message_new_method_call("org.bluez",btadrr_path,"org.bluez.AudioSource","Connect");

here btaddre_path is my bluetooth device path which is already paired...

in Python

manager = dbus.Interface(bus.get_object("org.bluez", "/"), "org.bluez.Manager")

adapter = dbus.Interface(bus.get_object("org.bluez", manager.DefaultAdapter()), "org.bluez.Adapter");

audiosrc = dbus.Interface(bus.get_object("org.bluez", adapter.FindDevice(bdaddr)), "org.bluez.AudioSource");

audiosrc.Connect()
