I am trying to send a command to a device using Orion + Ultralight 2.0. The device is registered and I can send measures easily. I want to work in the pooling mode in order to execute commands, but when I execute the updateContext operation, IDAS doesn't found the entity. Here are the configuration and the logs:
Configuration:
var config = {};
config.mqtt = {
host: 'mosquitto',
port: 1883
};
config.http = {
port: 7896
};
config.iota = {
logLevel: 'DEBUG',
timestamp: true,
contextBroker: {
host: 'MY_IP',
port: '1026'
},
server: {
port: 4041
},
deviceRegistry: {
type: 'mongodb'
},
mongodb: {
host: 'mongo',
port: '27017',
db: 'iotagentul'
},
types: {},
service: 'howtoService',
subservice: '/howto',
providerUrl: 'http://YIP:4041',
deviceRegistrationDuration: 'P1M',
defaultType: 'Thing'
};
config.defaultKey = 'TEF';
module.exports = config;
I have tried different IP's and routes, and at the end i tried with the public IP, assuring that there is communication from the outside to those ports.
Device registration:
curl -X POST \
http://MYIP:4041/iot/devices \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
-d '{
"devices": [{
"device_id": "muvone",
"protocol": "IoTA-UL",
"entity_name": "muvone",
"entity_type": "Thing",
"attributes": [{
"object_id": "t",
"name": "temperature",
"type": "Float"
}],
"commands": [{
"name":"blink",
"type": "command",
"value": "muvone@blink|%s"
}],
"static_attributes": []
}]
}'
Then I send some observations from a physical device and from POSTMAN:
curl -X POST \
'http://MYIP:7896/iot/d?i=muvone&k=TEF&getCmd=1' \
-H 'cache-control: no-cache' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
-d 'temperature|16'
Which actually updates the entity correctly, as can be seen in Orion Context Broker: Query:
curl -X GET \
http://MYIP:1026/v2/entities \
-H 'cache-control: no-cache' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
Response:
[
{
"id": "muvone",
"type": "Thing",
"TimeInstant": {
"type": "ISO8601",
"value": "2017-06-01T11:37:52.537Z",
"metadata": {}
},
"blink_info": {
"type": "commandResult",
"value": " ",
"metadata": {}
},
"blink_status": {
"type": "commandStatus",
"value": "UNKNOWN",
"metadata": {}
},
"temperature": {
"type": "Float",
"value": "16",
"metadata": {
"TimeInstant": {
"type": "ISO8601",
"value": "2017-06-01T11:37:52.537Z"
}
}
}
}
]
So now, If I want to send a command, I have done it in a lot of ways. I tried following this guide:
http://fiware-iot-stack.readthedocs.io/en/master/topics/device_connection/index.html
So I tried to use the following request:
curl -X PUT \
http://MYIP:1026/v2/entities \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
-d '{
"id": "muvone",
"type": "Thing",
"blink": {
"type" : "command",
"value" : "true"
}
}'
Which response is:
{
"error": "MethodNotAllowed",
"description": "method not allowed"
}
So I tried updating a single attribute, in this case the blink attribute, which is a command. This should trigger that the Orion Context Broker acts as a NGSI proxy and passes the request to the IoTAgent, which occurs. But the problem is that the IoTAgent doesn't find the entity, as it can be seen in the logs:
curl -X PUT \
'http://MYIP:1026/v2/entities/muvone/attrs/blink?type=Thing' \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
-d '{
"type": "command",
"value": "true"
}'
or
curl -X PUT \
'http://MYIP:1026/v2/entities/muvone/attrs/blink?type=Thing' \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
-H 'postman-token: 6b42d06d-2a9f-3081-e315-bd9919aeded5' \
-d '{
"value": "true"
}'
Responds with:
{
"error": "NotFound",
"description": "The requested entity has not been found. Check type and id"
}
Edit: The get v2/entities to orion result, after issuing these requests is:
[
{
"id": "muvone",
"type": "Thing",
"TimeInstant": {
"type": "ISO8601",
"value": "2017-06-02T10:26:32.212Z",
"metadata": {}
},
"blink_info": {
"type": "commandResult",
"value": " ",
"metadata": {}
},
"blink_status": {
"type": "commandStatus",
"value": "UNKNOWN",
"metadata": {}
},
"temperature": {
"type": "Float",
"value": "26",
"metadata": {
"TimeInstant": {
"type": "ISO8601",
"value": "2017-06-02T10:26:32.212Z"
}
}
}
}
]
Now, having a look at Orion and IoTAgent logs, it can be seen that IoTAgent doesn't find the entity:

In the mongo database, it can be seen that the registrations, entities and everything is set up correctly.
I have worked around this issue for days with no result. Any help will be appreciated. Thanks in advance
UPDATE
After using the v1 of the Orion API, the result is the same that the given by v2:
curl -X POST \
http://MYIP:1026/v1/updateContext \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'fiware-service: howtoService' \
-H 'fiware-servicepath: /howto' \
-d '{
"contextElements": [
{
"type": "Thing",
"isPattern": "false",
"id": "muvone",
"attributes": [

]
}
],
"updateAction": "UPDATE"
} '
Result:
{
"errorCode": {
"code": "404",
"reasonPhrase": "No context element found"
}
}
2nd UPDATE I have a service that sends the commands that I issue to the context broker. The difference is that if the command is defined in the device, it responses with the 404 error, but if it is not defined in the preprovision, it responds with the code 472:
Undefined command

GET /v2/entitiesresult after you do thePUT /v2/entities/muvone/attrs/blink?type=Thing, please? Thx! – fgalan
