[Bluez-users] hci0 problem after timeout

[Bluez-users] hci0 problem after timeout

[Rafael Vidal Aroca]

	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?

    After this, if i try:

    Can't init device hci0. Connection timed out(110)

       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.

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.

Marcel

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.
