Return-Path: From: Jakub Pawlowski To: linux-bluetooth@vger.kernel.org Cc: Jakub Pawlowski Subject: [PATCH v7 1/8] core: device: add device_set_rssi_with_delta Date: Tue, 31 Mar 2015 00:33:23 -0700 Message-Id: <1427787210-4436-2-git-send-email-jpawlowski@google.com> In-Reply-To: <1427787210-4436-1-git-send-email-jpawlowski@google.com> References: <1427787210-4436-1-git-send-email-jpawlowski@google.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch adds new method that allow to update RSSI value with given delta threshold. It will be used in upcoming patches with SetDiscoveryFilter, in order to disable delta threshold. --- src/device.c | 14 +++++++++++--- src/device.h | 2 ++ 2 files changed, 13 insertions(+), 3 deletions(-) diff --git a/src/device.c b/src/device.c index 8ad62d3..91dea27 100644 --- a/src/device.c +++ b/src/device.c @@ -83,6 +83,8 @@ #define MIN(a, b) ((a) < (b) ?
