Question:
How to realize the ERROR Path for Commands using MQTT-binding of the FIWARE IoT-Agent-JSON
Description:
from the FIWARE IoT-Agent-Json documentation I understand that there is the happy path and error path for command execution (https://fiware-iotagent-json.readthedocs.io/en/latest/usermanual.html#commands)
Using the MQTT-binding, sending a payload on the topic /json/<APIKey>/<DeviceId>/cmdexe always results in an update of the corresponding command-info to OK. This is fine as long the device does the right thing about receiving the command. However, how can I trigger an ERROR, e.g. the device receives the command, but can not execute it. Somehow with MQTT, I currently onyl understand the _info to be on either PENDING or OK once the IoT-Agent published the command to the device.
In which case will the _info udpated to ERROR? I could not find anything in the code about this scenario.
Thanks, for any help on this.
