Connect

def device_discovered(mac, name, rssi):

ble_connect(mac)

class Lamp:

# ...

def connect(self):

self.status = 'CONNECTED'

self._dbus = LampService(self.mac)

self._config = ConfigService(self.mac, "DeviceHiveVB")

self._controlpanel = ControlPanelService(self.mac)

ble.connect_to_signal("DeviceDiscovered", device_discovered)

ble_connect(self.mac)

Calling alljoyn bridge

bridge = dbus.Interface(

bus.get_object(DBUS_BRIDGE_NAME, DBUS_BRIDGE_PATH),

dbus_interface='com.devicehive.alljoyn.bridge')

bridge.AddService(

self._dbus.m_service_path, self._dbus.m_service_name,

ALLJOYN_LIGHT_PATH, ALLJOYN_LIGHT_NAME, INTROSPECT)

bridge.AddService(

self._config.m_service_path, self._config.m_service_name,

ALLJOYN_CONFIG_PATH, ALLJOYN_CONFIG_NAME, CONFIG_INTROSPECT)

bridge.StartAllJoyn(self._dbus.m_service_name)

Turn It On(Off)

def turnOnOff(self, state):

self.OnOff = state

if state:

print("***LAMP NOW IS ON***")

ble.GattWrite(

self.mac, SATECHI_COLOR_CHAR, '0f0d0300ffffffc800c800c8000059ffff')

else:

print("***LAMP NOW IS OFF***")

ble.GattWrite(

self.mac, SATECHI_COLOR_CHAR, '0f0d0300ffffff0000c800c8000091ffff')

Run

def worker():

time.sleep(2)

mac = 'd05fb831379f'

Lamp(mac, 'Virtual Lamp').connect()

# init d-bus

GObject.threads_init()

dbus.mainloop.glib.threads_init()

# start mainloop

loop = GObject.MainLoop()

worker_thread = threading.Thread(target=worker,)

worker_thread.start()

loop.run()
