Does the MQTT extension support persistent sessions in ThingWorx
Modified: 12-Mar-2024
Applies To
- ThingWorx Platform 6.5 to 9.3
Description
- Does the MQTT extension support persistent sessions?
- No cleansession parameter in the MQTT extension entities
- MQTT extension doesn't have a clean session parameter to configure
- When setting the Quality of service (the setting for publishing data) to 2 for MQTT connection Thing in ThingWorx to make sure all the messages accepted by the broker are delivered to ThingWorx, it still connects to the broker with the cleanSession flag set to true
- This can result in failure to retrieve stored messages when the connection is interrupted
- Messages sent while ThingWorx is down are not read after restart of ThingWorx
