+OpenMQTTGateway is able to scan all the BLE devices that advertise their data so as to do presence detection. 
+Added to that it retrieves the measures from the devices below. By default the data are read from the advertisements (no impact on device battery life). When a (c) is present after the model name, this means that the gateway connects to it so as to retrieve data. For some devices we may connect only to retrieve one or several parameters (the rest being advertised), in this case the (c) is placed with the parameter.
