I know Tobias has answered this but I thought you might be interested
in seeing a couple of code alternatives:
#!/usr/bin/env python3
import dbus
def get_iface_prop(iface, prop):
response = {}
bus = dbus.SystemBus()
mng = dbus.Interface(bus.get_object('org.bluez', '/'),
'org.freedesktop.DBus.ObjectManager')
for path, ifaces in mng.GetManagedObjects().items():
if iface in ifaces:
response[path] = ifaces[iface][prop]
return response
if __name__ == '__main__':
for k, v in get_iface_prop('org.bluez.Device1', 'Connected').items():
print('{0} is {1}'.format(k, v))
Gives an output something like:
$ ./connected_devices.py
/org/bluez/hci0/dev_F7_17_E4_09_C0_C6 is 1
/org/bluez/hci0/dev_E8_A9_41_CE_31_5A is 0
/org/bluez/hci0/dev_B0_B4_48_BE_5D_83 is 0
/org/bluez/hci0/dev_8C_2D_AA_44_0E_3A is 0
Hope that helps.
Cheers,
Barry
