猎户座蚊子JSON数据

Question

I have some issues with the Orion Context Broker. I am using raspberry pi to publish the JSON data to mosquitto broker that runs as a docker container. I can receive the data from the publisher, and the broker should pass the data to the Orion Context Broker. I created an entity like this:

curl localhost:1026/v2/entities -s -S -H 'Content-Type: application/json' -d @- <<EOF
{
  "id": "SensTemp",
  "type": "Sensor",
  "temperature": {
     "value": 28,
     "type": "Float"
   }
 }
EOF

I can update the temperature value manually without any problems using the curl command. The problem is that the data from my mosquitto container doesnt go to the Orion Context Broker. Here are my docker containers:

version: "3.3"
services:

          mongo-db:
            image: mongo:3.6
            hostname: mongo-db
            container_name: db-mongo
            expose:
             - "27017"
            ports:
             - "27017:27017"
            networks:
             - default
            command: --bind_ip_all --smallfiles

          orion:
             image: fiware/orion
             ports:
                 - "1026:1026"
             networks:
                 - default
             depends_on:
                 - mongo-db
             command: -dbhost mongo-db -logLevel DEBUG
             healthcheck:
                   test: ["CMD", "curl", "-f", "http://0.0.0.0:1026/version"]
                   interval: 1m
                   timeout: 10s
                   retries: 3

          mqtt:
            image: eclipse-mosquitto:latest
            container_name: mqtt
            ports:
              - "1883:1883"
              - "9001:9001"
            expose:
              - "1883"
              - "9001"
            volumes:
              - /opt/mosquitto/var/run:/var/run

Here is the proof of received data from my raspberry pi publisher:

How can I set up the Orion to get the data from my mosquitto container?

Answer 1

When yo create the device, Did you indicate the transport?

For example

 "device_id":   "streetLight001",
 "entity_name": "urn:ngsi-ld:StreetLight:001",
 "entity_type": "StreetLight",
 "protocol":    "PDI-IoTA-UltraLight",
 "transport":   "MQTT",
 "timezone":    "America/Bogota",

Answer 2

When yo create the device, Did you indicate the transport and attributes (see this image)? entity creation with atributes

Answer 3

Update! I was able to connect to the agent, the message is arriving from the mosquitto container. I only needed to create a service group and i had to create a registration using some REST orders (curl commands). but now it gives me the error of some kind, yes i know that nobody here likes screenshots but if you know how can i fix the problem thanks !!!!

Answer 4

Problem Solved, The problem was in the Agent. i was using Ultralight IOT agent instead of the JSON Agent
