From: Johan Hedberg Date: Wed, 16 Jul 2014 08:56:08 +0000 (+0300) Subject: Bluetooth: Track number of LE slave connections X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f8218dc6605a7b2af843f9ff5d66229a4a0b1c45;p=openwrt%2Fstaging%2Fblogic.git Bluetooth: Track number of LE slave connections Most (probably all) controllers can only deal with a single slave LE connection at a time. This patch adds a counter for such connections so that the number can be quickly looked up without iterating the connections list.
