• Hardware Platform (Jetson / GPU): Jetson Nano
• DeepStream Version: 5.0 GA
• JetPack Version (valid for Jetson only): 4.4 (L4T 32.4.3)
• Issue Type( questions, new requirements, bugs): Sudden error when publishing MQTT messages (AWS IoT Core)
• How to reproduce the issue ?: I have not been able to identify conditions to reproduce the error.
Hi everyone. I have a deepstream application running on a jetson nano in a “remote” location that I can access via VPN. This application uses PeopleNet to detect people and together with nvtracker and nvdsanalytics, it counts people who pass through a line. Finally send these results through MQTT (AWS IoT Core). After running for about a month without any inconvenience (only some manual restart of the application due to a configuration change), I started receiving these messages last Friday (Oct 16).
Upon reviewing the application, it is still running and continues to perform detections and counts, however it is not able to publish MQTT messages. By stopping and restarting the application it begins to publish messages without problems again. However, since that day, the problem has been repeated three times without following any apparent pattern.
I am not an expert on the subject, but it strikes me that I suddenly started having this problem without having made any changes to the application. Could it be because of an external factor? Has anyone had a similar problem? Is there a way to handle this error so that the connection can be restarted automatically?
As additional information, mention that I followed the steps of aws-iot-core-integration-with-nvidia-deepstream to publish data to AWS IoT Core and that the payload sent is customized.
