Hi folks/Marcel, The patch is attached. The basic structure to start the development of the "sdp", "network", "serial", ... was added. There are a lot not implemented methods. Regards, Claudio. >>>>Main Features 1. added multiple bt adapter support 2. added the structures to support profiles 3. Modified paths to "/org/bluez/Devices" and "/org/bluez/Manager". Where "Devices" is going to provide device configuration services currently provided by hciconfig tool. The "Manager" will handle services related to connection establishment and setup, including profiles, sdp and device discovery. >>>>Next Action 1. Move the functions to to suitable file names( eg: dbus-mgr.c and dbus-dev.c) 2. Define the device based path name. >>>>How Test 1. /org/bluez/Devices, device up $dbus-send --system --dest=org.bluez --type=method_call /org/bluez/Devices org.bluez.Devices.Up 2. /org/bluez/Manager, Device list $dbus-send --system --dest=org.bluez --type=method_call /org/bluez/Manager org.bluez.Manager.DeviceList comment: This service returns an array of devices. The reply signature is "a(ss)", where the first string is the device name(eg: hci0, hci1) and the second string is the bluetooth address. You have to develop a python client or a "c" client to see the content. 3. /org/bluez/Manager/default/Controller, Inquiry $dbus-send --system --dest=org.bluez --type=method_call /org/bluez/Manager/default/Controller org.bluez.Manager.Inquiry byte:4 byte:10 uint16:0 or $dbus-send --system --dest=org.bluez --type=method_call /org/bluez/Manager/hci0/Controller org.bluez.Manager.Inquiry byte:4 byte:10 uint16:0 comment: This service returns an array of devices.
