From 4a3ee763ba797e0489b7e9fd8810ae087c2a7504 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 15 Mar 2013 17:07:12 -0500 Subject: [PATCH] Bluetooth: Update page scan parameters after successful write commands The page scan parameters (interval, window and type) stored in struct hci_dev should not only be updated after successful reads but also after successful writes. This patch adds the necessary handlers for the write command complete events and updates the stored values through them.
