2017-01-27 14:00:54 +0100 | answered a question | Tourguide App: problem sending data to sensor Ok, I sorted it out finally. It is related to the "entitytype" set when registering the sensor. I thougth I had to put it to "sensor", but I should have put it to the "entityname"'s type, which is "Restaurant". So the "tooManyResult" error I got was, as explained by jmcantera, related to different entities with same id but of different types. But we can effectiveley request an entity to see if the sensor was added before sending any sensor data update, as described in "Register a new sensor with the IoT Agent" in this doc: http://fiwaretourguide.readthedocs.io... |

2017-01-20 14:41:00 +0100 | commented answer | Tourguide App: problem sending data to sensor Hello, Thanks for your answer. If I look at the second link you provide, the last request at the end of "Register a new sensor with the IoT Agent" section tells: "We can do a request to orion for the restaurant and see if the new attribute has been added". This is before sending data, same as I do. |

2017-01-19 09:51:36 +0100 | asked a question | Tourguide App: problem sending data to sensor Hello, In the Tourguide App documentation, I can't see the attributes of the created sensor when following Manage IoT Data section. I just tried with a clean install of the tutorial, and this is what I get: (if anybody can tell me how I can make the json format look nicer in markdown syntax, any hint would be welcome... I'll update the code below) I post following request to create the IDAS service:
with header:
then I registered the sensor as following with the same headers
(both requests return 200 and 201 with {}, so it looks fine) Then querying the entity to see if the attributes are there with:
gives me this answer:
--> So no sign of the added attribute... Why is that? If I do the request without "type=Restaurant" i get:
Why are there more than one result on a request specifying an entity with a unique id? |

Maybe they can give a hint about that? |

2017-01-18 09:31:59 +0100 | asked a question | Tourguide update sensor value Hi, I'm trying to send sensor data to the fiware notebook instance "Fiware Tour Guide for newbies" here But I am stuck at understanding the IoT section. You can see in my tests here that I get an error when sending sensor data: "name":"ENTITYGENERICERROR","message":"Error accesing entity data for device: thing:myKitchen-sensor-0115206c51f60b48b77e4c937835795c33bb953f of type: thing" Thanks in advance for your help! EDIT: Even the example on the this page has the same result if I execute it without modifying it. I get the same error: {"name":"ENTITYGENERICERROR","message":"Error accesing entity data for device: thing:restaurant-sensor-0115206c51f60b48b77e4c937835795c33bb953f of type: thing"} |
