QUESTION
Currently I've got my own LoRaWAN network, with around 45 devices sending data with this payload: ID=D0001&T=23&H=60 where ID is the sensorId; T-Temperature; H - Humidity.
What steps do I have to make next to get context from my devices?
These are the steps that I've made:
1 - Installed IoT-Agent Ultralight
2 - Configured MQTT on the config.js file with my MQTT data
config.mqtt = {
host: 'HOST_NAME',
port: 1883,
protocol : mqtt,
username: 'USERNAME',
password: 'PASSWORD',
retain: false,
retries: 5,
retryTime: 5,
keepalive: 0,
avoidLeadingSlash: false
};
3 - IoTAgent-ul (node bin/iot-agentul), getting this message: time=2020-12-01T10:44:48.197Z | lvl=INFO | corr=526cdc56-62b8-4791-b95d-f5110ca18b7e | trans=526cdc56-62b8-4791-b95d-f5110ca18b7e | op=IOTAUL.MQTT.Binding | from=n/a | srv=n/a | subsrv=n/a | msg=connected | comp=IoTAgent
...ANSWER
Answered 2020-Dec-02 at 15:41It is unclear whether you need the IoT Agent for Ultralight or the IoT Agent for LoRaWAN. Ultralight is a payload syntax, the Ultralight IoT Agent supports HTTP, MQTT and AMPQ transports. LoRaWAN is a transport, it supports a couple of COAP protocols.
If you are really sending LoRa COAP messages then you'll need the LoRaWAN agent.
If you are using Ultralight over MQTT, then your message payload should look like this

orion version : 2.3.0 iotagent-ul version : 1.12.0
I am using fiware and iotagent over mqtt. I want to send commands to some devices with different values. I have followed https://github.com/FIWARE/tutorials.IoT-over-MQTT and read some documentation. After provisionning a service group (with apikey: 123456) and an actuator, I can send commands with values by following the iota URL :
