From c19902405ebe92a17efe041cae9a3584c3b182e5 Mon Sep 17 00:00:00 2001 From: Matt Ranostay Date: Tue, 30 Oct 2018 11:39:25 -0700 Subject: binding: bluetooth: add initial discovery filter support Allow clients to request devices only with certain profile UUIDs to be displayed in an discovery scan. This allows to filter out things like location tokens, smart scales, and etc which can't possibly have a2dp or hfp profiles for instance. NOTE: This is a write only setting. In the future should be read/write to see current discovery filters.
