From a1e0db855ec3168e80a32ed6c35b074bcfc11178 Mon Sep 17 00:00:00 2001 From: Jean-Michel Trivi Date: Thu, 2 Feb 2023 18:12:56 +0000 Subject: [PATCH] AudioService: handle BT profile disconnections The BT A2DP, LE and HearingAid proxies to the BT service were initialized on profile connection, but were never reset on profile disconnection in BtHelper. Wrapped the calls to the BT proxies with try/catch as the notification that a profile disconnected can happen while the proxy is used.
