From 48ce62c4fae7e817d9018020345bbe30a6b9c446 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 12 Jan 2015 09:21:26 -0800 Subject: [PATCH] Bluetooth: Read stored link key information when powering on controller The information about max stored link keys and current stored link keys should be read at controller initialization. So issue HCI Read Stored Link Key command with BDADDR_ANY and read_all flag set to 0x01 to retrieve this information.
