From: Lukasz Rymanowski <lukasz.rymanowski@xxxxxxxxx> This patch introduces API to monitor connection parameters. New device properties are introduced: ConnectionRSSI, ConnectionTXPower and ConnectionTXPowerMax. Client can request to poll for updates of RSSI and TX power via Start- and StopConnectionMonitor methods. --- doc/device-api.txt | 56 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) diff --git a/doc/device-api.txt b/doc/device-api.txt index 577ee60..67f573c 100644 --- a/doc/device-api.txt +++ b/doc/device-api.txt @@ -100,6 +100,35 @@ Methods void Connect() Possible errors: org.bluez.Error.DoesNotExist org.bluez.Error.Failed + + void StartConnectionMonitor() + + This method starts connection monitor session.
