Im save dump with -w option. hcidump fail only with -V option. Im tested this tool on the same system but use glibc-2.3.2. The result is the same.

I can normally load this tool under gdbserver. But i can`t normally connect to gdbserver from scratchbox gdb. On command list gdb get next
answer:

(gdb) list
1 /home/tsavola/sb-toolchains/gcc/glibc/work/glibc_build/csu/crti.S:
No such file or directory.
in /home/tsavola/sb-toolchains/gcc/glibc/work/glibc_build/csu/crti.S

All my another programme loading and debugging fine. Do you know that does it mean?

Regurds. Bizyukov Artem.

the problem is easy, because it is not a valid HCI frame and hcidump is not doing any robustness checks.

A PIN code reply must include the BD_ADDR and not the connection handle. Install bluez-utils-2.21 (or from CVS) and try again.

Hello Marcel
I used the latest utils and libs. And those dump i record with:

OMAP5912OSK:~# hcitool
hcitool - HCI Tool ver 2.21
MAP5912OSK:~# hcidump --help
HCI sniffer - Bluetooth packet analyzer ver 1.25

I`m thin this bug is not critical. In my previous post "L2CAP channel" i describe my main problem. I cant connect to my board through L2CAP channel.

Kernel answer "Connection pending". But i ned that kernel enswer "Connection successful" without "Connection pending". I am write application that must communicate with already exist big PC application, and i can`t change it. How i must open socket, or set it parametrs, for succesful connect with a PC application?

Regards.
Bizyukov Artem.
