Subject: [PATCH] Fast Advertising Interval
Date: Mon, 8 Jul 2019 11:36:13 +0530 [thread overview]
Message-ID: <1562565973-20657-1-git-send-email-spoorthix.k@intel.com> (raw)
From: Spoorthi Ravishankar Koppad <spoorthix.k@intel.com>
Changes made to add support for fast advertising interval
as per core 4.1 specification, section 9.3.11.2.
A peripheral device entering any of the following GAP modes and
sending either non-connectable advertising events or scannable
undirected advertising events should use adv_fast_interval2
(100ms - 150ms) for adv_fast_period(30s).
- Non-Discoverable Mode
- Non-Connectable Mode
- Limited Discoverable Mode
- General Discoverable Mode
