[Bluez-devel] pand problem

[Vijayakumar]

Hi all,

My linux kernel version is 2.4.20-8
Applied 2.4.18 mh patch

      My pand connection gets disconnected after about 4-5 hrs. I 
established pand connection between 2 dongles and ran multiple telnet 
sessions (each running ls -lR in an infinite loop) and an ftp 
session(transfers files repeatedly between the machines in an infinite 
loop).After some 4-5 hrs i found that the pand onnection no longer existed.

And I found "NET unregister event not supported" in my system log 
messages....Below is my system log...

Hi Vijayakumar,

this kernel is quite old and the -mh patch for 2.4.18 can't be applied
to a 2.4.20 kernel. Why don't you switch to the latest 2.6 kernel?

Run "hcidump -X -V" and see why the connection gets terminated.

This is hotplug stuff and not Bluetooth related.

Marcel

Hi Marcel,

Sorry for the incorrect information, my kernel is 2.4.18.

Upgrading to a latest kernel is not possible right now, it is beyond my 
control

I got the following on my board side (2.4.18 kernel)

< ACL data: handle 42 flags 0x02 dlen 192
< ACL data: handle 42 flags 0x02 dlen 192
< ACL data: handle 42 flags 0x01 dlen 192
> ACL data: handle 42 flags 0x02 dlen 512
> ACL data: handle 42 flags 0x01 dlen 512
> HCI Event: Disconn Complete (0x05) plen 4
    status 0x00 handle 42 reason 0x08
    Reason: Connection Timeout

and on the pc side (running redhat linux )

> ACL data: handle 41 flags 0x01 dlen 192
> HCI Event: Disconn Complete (0x05) plen 4
    status 0x00 handle 41 reason 0x08
    Reason: Connection Timeout

Can you give some clues?
Regards,
Vijayakumar.
