Hi,
i tried today to discover devices with apitest (instead of "hcitool scan"),
but it did not work:
seife@strolchi:~> apitest DiscoverDevices
None
and it returns immediately. So i tried my luck with direct "dbus-send":
seife@strolchi:~> dbus-send --system --dest=3Dorg.bluez --print-reply /org/=
bluez/hci0 org.bluez.Adapter.DiscoverDevices
method return sender=3D:1.541 -> dest=3D:1.867
No luck either.
I always get this in my syslog from hcid:
Oct 19 13:52:39 strolchi hcid[17330]: Introspect path:/org/bluez
Oct 19 13:52:39 strolchi hcid[17330]: Introspect path:/org/bluez/hci0
Oct 19 13:52:39 strolchi hcid[17330]: name_listener_add(:1.869)
Oct 19 13:52:39 strolchi hcid[17330]: DiscoverDevices requestor at :1.869 e=
xited before the operation finished
Oct 19 13:52:39 strolchi hcid[17330]: name_listener_remove(:1.869)
Oct 19 13:52:39 strolchi hcid[17330]: remove_name_listener: no listener for=
:1.869
So why doesn't the dbus call block? I also tried with a "apitest -l"
running in parallel, to see if this would get something discovered, but it
didn't:
seife@strolchi:~> apitest -l
Listening for events...
DiscoveryStarted - /org/bluez/hci0:
DiscoveryCompleted - /org/bluez/hci0:
DiscoveryStarted - /org/bluez/hci0:
DiscoveryCompleted - /org/bluez/hci0:
Caught signal, exiting
So am i doing something wrong?
I'm running bluez-{libs,utils} version 3.7 on 2.6.18.

I like it :-) I already had tried apitest -l DiscoverDevices, but it did
not work.

You need to keep the calling application running, because otherwise hcid
will stop the discovery. That is actually what you see in syslog.
It is not blocking, because this is simply not a blocking task. You
might wanna have a look at this blog on how to do it with Python:
