Problem with virtual IoT devices

Open DiEVeXx opened this issue 6 years ago • 2 comments

I'm trying to follow Robot's example: https://fiware-iotagent-lwm2m.readthedocs.io/en/latest/deviceProvisioning/

Using dynamic provisioning in the latest stable version of Fiware/Orion. Virtual Device data: (following this: https://github.com/telefonicaid/lwm2m-node-lib)

create /7392/0
set /7392/0 1 79
set /7392/0 2 "First robot here"
set /7392/0 3 "[0, 0]"
connect 127.0.0.1 5683 robot1 /
list

Here I show the Dockerfile:

retrieve entities v2:

  -H 'cache-control: no-cache' \
  -H 'fiware-service: Factory' \

returns me:

Well, now i cant access to lazy values or modify them

curl -X POST \

  -H 'fiware-service: Factory' \
  -H 'fiware-servicepath: /robots' \
  -d '{
	"entities": [
		{
			"type": "Robot",
			"isPattern": "false",
			"id": "robot1"
		}
	],
	"attributes": [

	]
}'

returns:

    "errorCode": {
        "code": "404",
        "reasonPhrase": "No context element found",
        "details": "No device was found with id:robot1"
    }
}

I could also show the log when I try to modify the value of the 'Message' lazy attribute. but this issue seems long enough.

It works flawless using this docker images: iotagent: hopu/lwm2m-iotagent:observe-and-read orion: fiware/orion:2.0.0

As you can see in https://fiware-iotagent-lwm2m.readthedocs.io/en/latest/deviceProvisioning/, you should use fiware-service in the headers of your requests in lowercase. So instead of Factory, please use factory.

Also confirm the name of the entity in the Context Broker. In my tests, instead of robot1 is Robot:robot1.

Hi, after the changes I'm having new problems. I just deleted all my DB and deleted my service provisioning. I just changed the fiware-service to factory and removed the line in the dynamic device provisioning "entity_name": "robot1", to make the system concatenate the entity_type:device_id for the id.

Orion returns in retrieve entities:

[
    {
        "id": "Robot:robot1",
        "type": "Robot",
        "Battery": {
            "type": "number",
            "value": " ",
            "metadata": {}
        },
        "Position_info": {
            "type": "commandResult",
            "value": " ",
            "metadata": {}
        },
        "Position_status": {
            "type": "commandStatus",
            "value": "UNKNOWN",
            "metadata": {}
        },
        "Message": {
            "type": "string",
            "value": "First robot here",
            "metadata": {}
        },
        "Position": {
            "type": "string",
            "value": "[0, 0]",
            "metadata": {}
        }
    }
]

First question: Why is IoTAgent uploading lazy attributes to Orion? So now, my queryContext request for a lazy attribute is this:

curl -X POST \
  http://192.168.1.32:1026/v1/queryContext \
  -H 'Accept: application/json' \
  -H 'Content-Type: application/json' \
  -H 'Postman-Token: 00efb112-2917-404a-8fc1-da6de93716a5' \
  -H 'cache-control: no-cache' \
  -H 'fiware-service: factory' \
  -H 'fiware-servicepath: /robots' \
  -d '{
	"entities": [
		{
			"type": "Robot",
			"isPattern": "false",
			"id": "Robot:robot1"
		}
	],
	"attributes": [
		"Message"
	]
}'

it returns:

{
    "contextResponses": [
        {
            "contextElement": {
                "type": "Robot",
                "isPattern": "false",
                "id": "Robot:robot1",
                "attributes": [
                    {
                        "name": "Message",
                        "type": "string",
                        "value": "First robot here"
                    }
                ]
            },
            "statusCode": {
                "code": "200",
                "reasonPhrase": "OK"
            }
        }
    ]
}

But when I try to update the lazy 'Message' value using:

curl -X POST \
  http://192.168.1.32:1026/v1/updatecontext \
  -H 'Accept: application/json' \
  -H 'Content-Type: application/json' \
  -H 'Postman-Token: 1ccc1d90-9172-4a85-93aa-5a2893a4fb61' \
  -H 'cache-control: no-cache' \
  -H 'fiware-service: factory' \
  -H 'fiware-servicepath: /robots' \
  -d '{
	"contextElements": [
		{
			"type": "Robot",
			"isPattern": "false",
			"id": "Robot:robot1",
			"attributes": [
				{
					"name": "Message",
					"type": "string",
					"value": "SOS!"
				}
			]
		}
	],
	"updateAction": "UPDATE"
}'

I get:

{
    "errorCode": {
        "code": "404",
        "reasonPhrase": "No context element found",
        "details": "error forwarding update"
    }
}

this is the log:
