Return-Path: From: Arman Uguray To: linux-bluetooth@vger.kernel.org Cc: Arman Uguray Subject: [PATCH BlueZ] core: Reduce RSSI delta threshold for RSSI property updates on Device1. Date: Mon, 29 Sep 2014 15:16:04 -0700 Message-Id: <1412028964-5298-1-git-send-email-armansito@chromium.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Currently the daemon does not update the RSSI property of a device object unless it sees a change of at least 8 dBm. This is too large for proximity use cases involving changes in distance within 4-5 feet. This patch reduces the threshold to 2 dBm to address this. --- src/device.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/device.c b/src/device.c index 875a5c5..821549e 100644 --- a/src/device.c +++ b/src/device.c @@ -4094,8 +4094,8 @@ void device_set_rssi(struct btd_device *device, int8_t rssi) else delta = rssi - device->rssi; - /* only report changes of 8 dBm or more */ - if (delta < 8) + /* only report changes of 2 dBm or more */ + if (delta < 2) return; DBG("rssi %d delta %d", rssi, delta); -- 2.1.0.rc2.206.gedb03e5
