From ff5cd29f5cb8de0f0bc9016874ddde467d4b0c85 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 25 Mar 2014 14:40:52 +0200 Subject: Bluetooth: Store also RSSI for pending advertising reports Especially in crowded environments it can become frequent that we have to send out whatever pending event there is stored. Since user space has its own filtering of small RSSI changes sending a 0 value will essentially force user space to wake up the higher layers (e.g. over D-Bus) even though the RSSI didn't actually change more than the threshold value. This patch adds storing also of the RSSI for pending advertising reports so that we report an as accurate RSSI as possible when we have to send out the stored information to user space.
