I just would add that with hardware scheduler DeviceDisappeared signal
works fine if there two remote devices in the field, and doesn't work if
there is only one remote device:
---
# Now there only 00:16:B8:53:5F:17 is turned on
Fri May 1 20:36:48 2009 Signal: DeviceFound 00:16:B8:53:5F:17
# Now I turn off 00:16:B8:53:5F:17 and wait, but no signal being emitted...
# So, I turn on 00:02:76:16:F6:8F
Fri May 1 20:38:52 2009 Signal: DeviceFound 00:02:76:16:F6:8F
Fri May 1 20:39:01 2009 Signal: DeviceDisappeared 00:16:B8:53:5F:17
# So new device appearing causes emitting DeviceDisappeared signal for
device that was turned off some time ago

P.S. I use BlueZ 4.36

Hi! I have some troubles with using DeviceFound and DeviceDisappeared
signals. I use simple test script: http://pastebin.com/m45de7894 .
There are two cases: if I use software inquire scheduler and if I use
hardware one.
Hardware scheduler. Bluetooth module in phone is on and I run script:

ilya@ilya-laptop:~/blue$ python fodis.py
Fri May 1 16:36:44 2009 Signal: DeviceFound 00:16:B8:53:5F:17

And no more signals. Then I wait 2 mins, turn off Bluetooth in phone
and wait 2 more mins, but no one signal is emitted.
I don't know if DeviceFound signal should be emitted on every inquire,
maybe not. But I'm sure DeviceDisappeared signal should be emitted at
least once :)
Software scheduler ("DiscoverSchedulerInterval = 1" at main.conf).

Fri May 1 16:45:23 2009 Signal: DeviceFound 00:16:B8:53:5F:17
### At this moment I turn off Bluetooth in phone
Fri May 1 16:45:43 2009 Signal: DeviceDisappeared 00:16:B8:53:5F:17

So, both signals was emitted on every inquiry. I think this is wrong
behavior. Am I right?
And DeviceDisappeared was emitted once after remote device was
actually turned off. That's good :)
