From 4b580614e1435628490a1762726638546f3a5e4e Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sat, 19 Oct 2013 23:38:21 +0300 Subject: [PATCH] Bluetooth: Fix sending write_scan_enable when BR/EDR is disabled We should only send the HCI_Write_Scan_Enable command from mgmt_set_powered_failed() when BR/EDR support is enabled. This is particularly important when the discoverable setting is also tied to LE.
