I am following the tutorial, but I have encountered with some problems with the commands. I am deploying the Scorpio NGSI-LD version of the tutorial.
As far as I know, the are two types of commands to configure something on an IoT Device:
Push command: The IoT Agent calls the IoT device's public address to send the command.
Polling command: The IoT Agent brings the command to the IoT device in the next iteration between the device and IoTAgent (MQTT Cmd topic subscription or HTTP Reponse after the next report).
I believe the tutorial follows the push command approach because the endpoint is defined during device provisioning. However, in a real-world scenario, an IoT device might not have a public IP address to receive configurations and should follow the polling command way.
Does the polling command work with IoTAgent-JSON or UL and the Scorpio Broker?
