Hi all,
I've made a software using DBUS StartPeriodicDiscovery monitoring in
(almost) realtime bluetooth devices in range.
I've already used this software with many computer and bluetooth dongles
without any problem (I've user it on a Asus eee with ubuntu and kernel
2.6.22, in a debian with kernel 2.6.23 and so on).
Now I've installed it on a ebox 2300SX
(http://www.compactpc.com.tw/ebox-2300SX.htm) using a customized debian
4.0 to run on compact flash with kernel 2.6.22.
I have two different problem :
- When I made a proxy call to StartPeriodicDiscovery sometime i receive
the response "Invalid argument", but if I made hciconfig hci0 reset
before running the problem doesn't appear
- Events generated by StartPeriodicDiscovery (eg. RemoteDeviceFound) are
never called
I can see the led of the bluetooth dongle blinking whene proxy call to
StartPeriodicDiscovery doesn't give error so I think periodic inquiry
is running (I have not verified with hcidump because at the moment isnt'
installed on the device and I can't install it )
The big difference from the 2300sx and the other installation is it
doesn't have math coporcessor so I have compiled the kernel to support
math emulation but I can't think this is the cause of my problems (why
bluez should use math coprocessor?). Also in the dmesg of the device I
found some error about ACPI ("ACPI: Unable to load the System
Description Tables" and "pnp: PnP ACPI: disabled"), I'm not expert of
ACPI but I think may cause some problems to usb devices...
Can someone give me a starting point to found the problem?
Many thanks
Fabrizio

I try to give more info about the problem hoping someone can give me
a little help.
I compiled the example from : http://wiki.bluez.org/wiki/HOWTO/
DiscoveringDevices (the "glib with C" one), used on laptop with
ubuntu :all ok, on a pc with debian :all ok, on ebox 2300sx with
debian 4.0 NOTHING (no errors no responses).
- dbus is running
- hcid is running
- if I make "hcitool scan" I can see the nearest bluetooth devices
- In syslog the only messages are "hcid[1794]: name_listener_add(:
1.1)" and "hcid[1794]: DiscoverDevices requestor at :1.1 exited
before the operation finished" (I've stopped the program after about
6/7 minutes of no-output)
I think problem is dbus related but I don't know where to look, I
also tried "dbus-send --system --type=method_call --print-reply --
dest=org.bluez /org/bluez/hci0 org.bluez.Adapter.GetMode" to interact
with dbus and all works fine so the problem may be in Discovery
related methods.
Suggestion?
Many thanks

Hi Fabrizio,
Discover process is automatically canceled when the client exits.
dbus-send will not work, try d-feet or other client that keeps the
D-Bus connection opened.
Regards,
Claudio.
