From 0ad06aa6a7682319bb1adcc187a1fa8db6b2da2c Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 11 Nov 2015 14:44:57 +0200 Subject: [PATCH] Bluetooth: Fix specifying role for LE connections The hci_connect_le_scan() is (as the name implies) a master/central role API, so it makes no sense in passing a role parameter to it. At the same time this patch also fixes the direct advertising support for LE L2CAP sockets where we now call the more appropriate hci_le_connect() API if slave/peripheral role is desired.
