Subject: How to enable "util_debug" function in att.c

Hello,
How to see output log from "util_debug" function in att.c
I searched it for few days but I don't have any clue yet.
How can I see the logs in console?
(Env. - linux and bluez5.41.)

I found enabling daemon log by adding "-d" flag in bluetooth.service
file but it's not what I want.



Thanks,
Calvin

Usually the code linking with bt_att needs to call bt_att_set_debug:

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/src/shared/att.h#n51

This is done for example by test-gatt:
