From c4f1f408168cd6a83d973e98e1cd1888e4d3d907 Mon Sep 17 00:00:00 2001 From: Howard Chung Date: Thu, 26 Nov 2020 12:22:21 +0800 Subject: Bluetooth: Interleave with allowlist scan This patch implements the interleaving between allowlist scan and no-filter scan. It'll be used to save power when at least one monitor is registered and at least one pending connection or one device to be scanned for. The durations of the allowlist scan and the no-filter scan are controlled by MGMT command: Set Default System Configuration. The default values are set randomly for now.
