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 can't use it because debian on this device is customized to fit in a
512Mb compact flash and I don't have all X11 Gnome etc.. stuff...
I'm trying to make a new kernel supposing the problem may be in it.
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.

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
