+Question:+
Commands in IotAgent Ultralight 2.0 FIWARE
+Description:+
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 at 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"
}
Now, having a look at Orion and IoTAgent logs, it can be seen that IoTAgent doesn't find the entity:

+Question:+
Commands in IotAgent Ultralight 2.0 FIWARE
+Description:+
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 = {

config.http = {

};
config.iota = {

};
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",

"type": "Float"
}],
"commands": [{
"name":"blink",
"type": "command",
"value": "muvone at 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 \

Response:

}
}
}
}
]
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 '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"
}
Now, having a look at Orion and IoTAgent logs, it can be seen that IoTAgent doesn't find the entity:

I have worked around this issue for days with no result.
Any help will be appreciated. Thanks in advance

> 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:

> Device registration:

> 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:

> http://MYIP:1026/v2/entities \

> 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"
> }
> Now, having a look at Orion and IoTAgent logs, it can be seen that IoTAgent doesn't find the entity:
> Orion logs to the request:
