From 8208f5a9d435e58ee7f53a24d9ccbe7787944537 Mon Sep 17 00:00:00 2001 From: Miao-chen Chou Date: Wed, 17 Jun 2020 16:39:18 +0200 Subject: Bluetooth: Update background scan and report device based on advertisement monitors This calls hci_update_background_scan() when there is any update on the advertisement monitors. If there is at least one advertisement monitor, the filtering policy of scan parameters should be 0x00. This also reports device found mgmt events if there is at least one monitor. The following cases were tested with btmgmt advmon-* commands. (1) add a ADV monitor and observe that the passive scanning is triggered. (2) remove the last ADV monitor and observe that the passive scanning is terminated. (3) with a LE peripheral paired, repeat (1) and observe the passive scanning continues. (4) with a LE peripheral paired, repeat (2) and observe the passive scanning continues. (5) with a ADV monitor, suspend/resume the host and observe the passive scanning continues.
