Subject: [PATCH v2 1/8] doc/gatt-api: Add Handle property
Date: Wed, 30 Jan 2019 15:54:17 +0200
Message-ID: <20190130135424.2091-1-luiz.dentz@gmail.com> (raw)

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

When acting as server it is useful to select where to allocate the
handle for an attribute so it can be restored in the same position when
restarting the daemon or rebooting the system.

In order to do that the application also needs to know in which handle
the attribute is allocated the very first time it is registered, this
also allows for a better integration with PTS and tools like auto-pts
which needs to know the handles where the attributes have been
allocated.
---
 v2: Fixes inserting characteristics and descriptors with handle 0x0000,
 add a patch to enable list-attribute to list with local attributes and
 print changes to attribute Handle property.
