[Fiware-lab-help] No measurements in CB Entity when sent via IDAS UL2.0

[Just van den Broecke]

Hi,

I have been trying to get UL2.0 via IDAS to the CB working:
- using latest GitHub 
https://github.com/telefonicaid/fiware-figway/tree/master/python-IDAS4 
scripts
- following the tutorials in particular 
http://www.slideshare.net/FI-WARE/fiware-iotidasintroul20v2

I have a FI-WARE Lab account with token generated. Changed the 
config.ini file:
[user]
# Please, configure here your username at FIWARE Cloud and a valid 
Oauth2.0 TOKEN for your user (you can use get_token.py to obtain a valid 
TOKEN).
username=MY_USERNAME
token=MY_TOKEN

[contextbroker]
host=130.206.80.40
port=1026
OAuth=no
# Here you need to specify the ContextBroker database you are querying.
# Leave it blank if you want the general database or the IDAS service if 
you are looking for IoT devices connected by you.
# fiware_service=
fiware_service=bus_auto
fiware-service-path=/

[idas]
host=130.206.80.40
adminport=5371
ul20port=5371
OAuth=no
# Here you need to configure the IDAS service your devices will be 
sending data to.
# By default the OpenIoT service is provided.
# fiware-service=fiwareiot
fiware-service=bus_auto
fiware-service-path=/
#apikey=4jggokgpepnvsb2uv4s40d59ov
apikey=4jggokgpepnvsb2uv4s40d59ov

[local]
#Choose here your System type. Examples: RaspberryPI, MACOSX, Linux, ...
host_type=MACOSX
# Here please add a unique identifier for you. Suggestion: the 3 lower 
hexa bytes of your Ethernet MAC. E.g. 79:ed:af
# Also you may use your e-mail address.
host_id=a0:11:00

I used the SENSOR_TEMP template, including the 'protocol' field 
(PDI-IoTA-UltraLight which as the first problem I stumbled upon):


	{
	 "devices": [
	    { "device_id": "DEV_ID",
	      "entity_name": "ENTITY_ID",
	      "entity_type": "thing",
	      "protocol": "PDI-IoTA-UltraLight",
	      "timezone": "Europe/Amsterdam",
	"attributes": [
	        { "object_id": "otemp",
	          "name": "temperature",
	          "type": "int"
	        } ],
	 "static_attributes": [
	        { "name": "att_name",
	          "type": "string",
	          "value": "value"
	        }
	       ]
	      }
	     ]
	    }

Now I can Register the device ok. Like
python RegisterDevice.py SENSOR_TEMP NexusPro Temp-Otterlo
and see it in Device List:
python ListDevices.py
I can send Observations like
  python SendObservation.py Temp-Otterlo 'otemp|17'

But in the ContextBroker I see the Entity but never the measurements, e.g.
python GetEntity.py Temp-Otterlo

             "isPattern": "false"
         }
     ],
     "attributes": []
}

...

         "type" : "thing",

         "id" : "Temp-Otterlo",
         "attributes" : [
           {
             "name" : "TimeInstant",
             "type" : "ISO8601",
             "value" : "2015-10-03T14:04:44.663133Z"
           },
           {
             "name" : "att_name",
             "type" : "string",
             "value" : "value",
             "metadatas" : [
               {
                 "name" : "TimeInstant",
                 "type" : "ISO8601",
                 "value" : "2015-10-03T14:04:44.663500Z"
               }
             ]
           }
         ]
       },
       "statusCode" : {
         "code" : "200",
         "reasonPhrase" : "OK"
       }
     }
   ]
}

I get an TimeInstant attribute strangely. I tried playing with settings 
of the .ini like fiware-service=fiwareiot, but to no avail. I am out of 
ideas. The documentation at
http://catalogue.fiware.org/enablers/backend-device-management-idas/instances/global-instance-ul20http-iot-agent-release-4
is talking about observations to be sent to port 8002 and setting 
"OpenIoT" service, but that failed.

Any help is appreciated.
