MQTT format problem with ThingsBoard

Recommended Posts

Hi everyone how are you?
we have a problem, we can't send messages with the unistream PLC with MQTT format to our iot platform on ThingsBoard. We think its because the format because the format of the json on ThingsBoard is {"temperature":42,"humidity":73} and the format in the plc is "temperature":42,"humidity":73

how can put in the start and the end of the message the {} symbols? or can we modify the json format on the plc?

If some one can do i regards a lot.
PD: im very new on PLC.
