Question:
FIWARE IoT Agent: how to send the location attribut to the contextBroker Entity?

Description:
I want to add location information to my entity in the contextBroker using the MQTT IoT Agent.
I followed this link to do so https://github.com/telefonicaid/fiware-IoTAgent-Cplusplus/blob/develop/doc/modules.md

My problem is that the attribut "location" was sent as String to the contextBroker not as "coords"

Here is what I sent to the MQTT IoT agent:

int qos = 1;
boolean retain = false;

String topic = "myKey/sensorId/location";
String payload= "12.5/14.5";

this.dataService.publish(topic, position.getBytes(), qos, retain, 2);

I assume that the location attribut in the contextBroker will have the type "coords", something like that:

{
"name":"position",
"type":"coords",
"value":"33.000,-3.234234",
"metadatas":[

]
}

But what I got in the contextBroker is this:

"location" : {
"value" : "12.5/14.5",
"type" : "string",
"md" : [

],
"creDate" : 1448382369,
"modDate" : 1448382369
}

What have I missed? Thanks in advance for your help!
