You're already checking for the value of callback earlier in the
function, so to avoid another check how about just move these
assignments right before the done: label?

* [PATCH BlueZ v0 00/18] GATT API: External Services
From: Claudio Takahasi @ 2014-01-09 16:38 UTC (permalink / raw)
To: linux-bluetooth; +Cc: claudio.takahasi, Claudio Takahasi
In-Reply-To: <1385585457-26951-1-git-send-email-claudio.takahasi@openbossa.org>
This patchset implements the minimal support for managing local
services declarations. Based on "[RFC BlueZ v2] doc: Add GATT API"
Changes from RFC v0 to PATCH v0:
* Changed copyright year : s/2013/2014
* Fixed coding style
* Added gatt-service binary to gitignore
* Added extra comment in the source code
Features:
* API for internal and external services declaration
* Unix socket for testing purpose: services are exported
through unix sockets to avoid breaking the current attribute
server.
How to test:
Run bluetoothd with EXPERIMENTAL flag
Replace bluetooth.conf and reload DBus settings
$gatttool -L --primary (or interactive mode)
Upstreaming plan (steps):
* GATT Server: External Services
* GATT Server: External Characteristics (Server)
* GATT Server: External Descriptors (Server)
* Remove ATTIO and automatic connection mechanism from userspace
* Replace attribute server
* Fix all GATT internal plugins
* GATT Client: Remote Services
* ...

Bluez. Applications must provide an object path and a dictionary of
options. Options dictionary will be used later to provide additional

This patch moves GATT UUIDs definitions to a common header. uuid.h contains
helper functions to manipulate Bluetooth UUIDs and some common BR/EDR services
UUIDs.
