[Bluez-devel] L2CAP & HCI trace

[Bluez-devel] L2CAP & HCI trace

[Filipa Duarte]

Hi,

I suppose that this is a quite stupid question but I
would like to know how can I have the same kind of
trace as Victor had (in the end of the e-mail)? 

The reason why is that I would like to identify which
are the functions (like l2cap_sock_sendmsg,
l2cap_chan_send, hci_send_acl, etc) used to send data
on the l2cap/hci layers. Could anyone give me any
direction to find this?

Many thanks,

Filipa

Hello, 

Try recompilating your kernel with the
CONFIG_BT_HCI_SOCK_DEBUG, CONFIG_BT_L2CAP_DEBUG, etc... (All the options
mentionned at the beginning of the files, in a block like : 

#ifndef CONFIG_BT_L2CAP_DEBUG
#undef  BT_DBG
#define BT_DBG(D...)
#endif

) enabled.

I've not tried it myself, but, reading to the code, I think it will
work.

I am a newbie in Linux/BlueZ matters and I am not sure
how to do this. Could you please explain?

By the way, does anybody has the l2cap and hci layers
implemented im User Space? I need to have those layers
running without OS... 

Cheers,

add a line with "#define CONFIG_BT_L2CAP_DEBUG" before this block and
recompile the module.

Actually it is possible to do this, but you are on the wrong mailing
list for this question ;)
