From c1d5dc4ac15be45c7061e207f06ad8dfba0c2170 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 8 Nov 2012 01:23:01 +0100 Subject: [PATCH] Bluetooth: Fix updating advertising state flags and data This patch adds a callback for the HCI_LE_Set_Advertise_Enable command. The callback is responsible for updating the HCI_LE_PERIPHERAL flag updating as well as updating the advertising data flags field to indicate undirected connectable advertising.
