From b2a5f2e1c127cb431df22e114998ff72eb4578c8 Mon Sep 17 00:00:00 2001 From: Yang Li Date: Tue, 1 Jul 2025 15:56:22 +0800 Subject: Bluetooth: hci_event: Add support for handling LE BIG Sync Lost event When the BIS source stops, the controller sends an LE BIG Sync Lost event (subevent 0x1E). Currently, this event is not handled, causing the BIS stream to remain active in BlueZ and preventing recovery.
