[Fiware-tech-help] [FIWARE] Problem with IDAS and ContextBroker

[Sancho, Juan]

Dear support team,

I'm experiencing some strange behavior while working with the IDAS and ContextBroker. I'm using the fiware-figway SDK repo, python version (https://github.com/telefonicaid/fiware-figway/tree/master/python-IDAS4/), on a CentOS 6.7 machine with Python 2.7.11; I've no firewall restrictions since I'm using a Virtual Machine in a dedicated server with a public ip.

Let me reproduce the issues I'm facing:

-          First, have a look at the default config.ini. The fiware-service is set to bus_auto, so I made both test with that variable to 'bus_auto' and also with 'OpenIoT' as explained here http://catalogue.fiware.org/enablers/backend-device-management-idas/instances:

o   << In order to get straight access to this instance, please use "OpenIoT" service.
The API-Key (shared secret to be known by devices to publish in a service) for "OpenIoT" is:
APIKEY: 4jggokgpepnvsb2uv4s40d59ov >>

o   Well, in fact I had to set fiware-service=openiot rather than fiware-service=OpenIoT because of the following:

§  << * Status Code: 400

* Response:

{"reason": "Malformed header","details": "Fiware-Service not accepted - a service string must not be longer than 50 characters and may only contain underscores and alphanumeric characters and lowercase"} >>

o   So, I made this tests in both fiware-service=bus_auto and fiware-service=openiot

o   I'm asking for a new token each day using get_token.py

-          I'm registering a device using Sensors_UL20/RegisterDevice.py with a model I've defined: SENSOR_MODEL_PI_01 (attached). It contains 2 attributes and 2 static_attributes. I had to add the property "protocol": "PDI-IoTA-UltraLight" so to make things work (the repo is not updated, but that issue remains opened https://github.com/telefonicaid/fiware-figway/issues/3).

o   Once registered, I launch ContextBroker/GetEntity.py in order to obtain info about my newly created Entity. However, the response shows a JSON in which only the static_attributes appear, not the non-static ones (in this model, temperature and voltage).

-          When it comes to sending measurements (observations), I'm using the script Sensors_UL20/SendObservation.py. If we attend to the default config.ini file, it's using the same port for the IDAS ADMIN REST API and for sending UL2.0 observations (port 5371). As explained here, http://catalogue.fiware.org/enablers/backend-device-management-idas/instances, port 8002 should be used for sending UL2.0 observations. However, that port seems to be closed/filtered in the instance, so no luck sending observations. In fact, it's quite confusing that I can still send observations using port #5371 and the response is a "Status Code 200", so ok.

Basically, I'm experiencing the same issues and applying same solutions as in here: http://stackoverflow.com/questions/32933813/fiware-no-observation-attributes-in-orion-cb-when-registered-sent-via-idas-ultr But still it doesn't work.

Any help would be more that appreciated.

Best Regards,
Juan
