[Bluez-users] BNEP connection destroing :(

[Bluez-users] BNEP connection destroing :(

[Todor Todorov]

Hi. I successful make a bnep connection between my laptop (with Slackware 10.0, kernel 2.4.26 with openmosix 
patch and latest version of bluez libs and bluez pand, but i tryed also with other versions) and desktop PC with 
Windows XP Pro, after few minutes  (not measured), on linux system the bnep0 interface was destroyed.

Attempting to reconnect with pand worked silently, but the bnep0 interface was not created. Workaround was to 
remove and re-insert the dongle on my laptop, then i recreate the bnep connection again.
I make a simple script for making bnep connection with windows machine:

#!/bin/sh
hciconfig hci0 up
#sdpd
#sdptool add LAN
echo "Making PAN connection"
#pand --role PANU -c 00:10:60:A6:1C:30 --service GN
pand --role PANU -c 00:10:60:A6:1C:30 --service PANU
echo "Wait for connection"
sleep 6
echo "Bring UP BNEP"
hcitool lst 00:10:60:A6:1C:30 0
ifconfig bnep0 10.0.0.2 netmask 255.255.255.0
ifconfig bnep0 up
route add default gw 10.0.0.1
rm /etc/resolv.conf
touch /etc/resolv.conf
echo "nameserver 10.13.0.1" > /etc/resolv.conf

This is my kernel config for bluez:

CONFIG_BLUEZ=y
CONFIG_BLUEZ_L2CAP=y
# CONFIG_BLUEZ_SCO is not set
CONFIG_BLUEZ_RFCOMM=y
CONFIG_BLUEZ_RFCOMM_TTY=y
CONFIG_BLUEZ_BNEP=y
# CONFIG_BLUEZ_BNEP_MC_FILTER is not set
# CONFIG_BLUEZ_BNEP_PROTO_FILTER is not set
# CONFIG_BLUEZ_CMTP is not set
CONFIG_BLUEZ_HCIUSB=y
# CONFIG_BLUEZ_USB_SCO is not set
# CONFIG_BLUEZ_HCIUART is not set
# CONFIG_BLUEZ_HCIBFUSB is not set
# CONFIG_BLUEZ_HCIDTL1 is not set
# CONFIG_BLUEZ_HCIBT3C is not set
# CONFIG_BLUEZ_HCIBLUECARD is not set
# CONFIG_BLUEZ_HCIBTUART is not set
# CONFIG_BLUEZ_HCIVHCI is not set

Help me to resolve this problem.
Thank you in advance.

run "hcidump -X -V" as root while connecting and see what really
happens.

OK.
First i run  run "hcidump -X -V", after that i make bnep connection and start normal internet work (surfing web sites 
and icq).
Here is the result:

this is the end of the result:

I forgot to say that i sharing my internet connection on windows machine with proxy (CC Proxy 6.0).
Also when i try to transfer one file up to 50MB, and connection was destroyed after nearly 20MB transfer, but when 
i re-plug the dongle and reconnect again the whole 50MB file was transfered. I tried also to ping the desktop PC with 
ping 60k and the connection whas imмediately destroyed. This i fix(i think so) with this "hcitool lst 00:10:60:A6:1C:
30 0"
This is tried also when i use windows on the laptop and desktop, and there isn't problem.

Hi Todor,

> < HCI Command: Disconnect (0x01|0x0006) plen 3
>     handle 41 reason 0x13
>     Reason: Remote User Teminated Connection

this means that we terminate the connection. This is funny, because I
have no idea why that happens. Maybe you should use a 2.6.11-rc5 kernel
instead of an old 2.4 kernel.

Regards

Marcel
