Hi guys, i made a bluetooth network from my linux box to my ipaq box,
but i'm having some problems. Both systems runs linux and bluez.

In PC side i use the folowing commands:

pand --listen --role GN
hciconfig hci0 -lm master,accept

Then on iPaq:

hcitool inq
pand --connect 00:80....
ifconfig bnep0 192.168.2.2 netmask 255.255.255.0

Back to PC:

ifconfig bnep0 192.168.2.1 netmask 255.255.255.0

Doing that i can ping and ssh to my ipaq pocket pc and can also use
internet through pc. But just for 30 seconds!!!!

After about 30 seconds the conection fails and pc's dmesg shows
nothing. I just get and error when trying to restart hci0:

	root@gemini:~# hciconfig hci0 down	
	root@gemini:~# hciconfig hci0 up
	Can't init device hci0. Connection timed out(110)

I really think the problem is in the pc side, and i'm having trouble
putting this D-Link DBT-120 usb bluetooth dongle to work since last year. Can anyone help or point solutions?

Distro: Debian Woody
Kernel: 2.4.22 (no from distro, i compiled)
hotplug: 2004_01_05 (latest)
bluefw: 1.0

Hope i gave enough info. Thanks in advance.

[]s Rafael.

give us the output of "hciconfig -a" for your devices. What kind of USB host controller do you have (lspci)? What USB host driver do you use?

Regards

Marcel

Ok:

Before starting hotplug system:

hciconfig -a show nothing

I use UHCI USB system.

Well, now after the timeout problem:

   root@gemini:~# hciconfig -a

       Manufacturer: Broadcom Corporation (15)

After this, if i try:

   root@gemini:~# hciconfig hci0 down
   root@gemini:~# hciconfig hci0 up 
   Can't init device hci0. Connection timed out(110)
root@gemini:~# hciconfig -a

       Link policy: HOLD SNIFF PARK
       Link mode: ACCEPT MASTER

I updated my kernel to 2.4.24 also yesterday, and the problem
persists. So, i have 2 problems: The conn that fails after some seconds and the hci0 that does not come back after that.

Thanks again.

[]s Rafael.

maybe it is this Broadcom device or maybe it is your USB chipset. What host driver do you use? usb-uhci or uhci? Try the other one. If you have access to a CSR donlge please try this.

Looks that the dongle problem was solved, but the connection still
fails after some time (a bit more now).

I changed from uhci to usb-uhci and now I can issue hciconfig hci0
up and down how many times I want without any problems. Seems that the PC box is clear now.

Now the question is: are IP connections using pand reliable? May not
pand be the problem?

Just to mention, after the failed connection, i have to disable and
enable bluetooth again on ipaq, because hcitool inq causes a message "timed out".

the iPAQ contains a CSR chip with an old firmware and maybe the interop between the Broadcom and the CSR Bluetooth chips is not very good. If you have access to another CSR based USB dongle please try this and tell us if the BNEP connection is still failing.

this is actually bad. Maybe a friend or a colleague has one that you can borrow for testing.

Well, i managed to make the connection i wanted using ppp over a
rfcomm channel. I works great with no timeouts :-)

I really don't know anyone here in my city that has a bluetooth
dongle, or even a csr based one.

I can't explain, why this works and BNEP not. Maybe you should try the latest 2.4.25-pre or 2.6.2-rc.
