From 3124b84309a0699c98bdc0ef1fc8cd5e058ad5fa Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sat, 12 Oct 2013 07:19:32 -0700 Subject: Bluetooth: Allow 3D profile to use security mode 4 level 0 The PSM 0x0021 is dedicated to the 3D profile and has permission to use security mode 4 level 0 for L2CAP connectionless unicast data transfers. When establishing a L2CAP connectionless channel on PSM 0x0021, it will no longer force Secure Simple Pairing.
