[Bug] Not sending Keep-alive about mqttx HOT 2 OPEN

Thank you for reporting the issue with MQTTX not sending Keep-Alive messages as expected in version v1.9.9. To help troubleshoot, you can enable debug logs to observe the ping requests, giving insights into what happens when the requests stop being sent.

The connection dropping after the application has been idle is a known issue related to MQTTX being built on Electron, where MQTT connections are managed at the UI layer rather than through Node.js. This can result in a different experience compared to tools like Node-Red. We're addressing this in the upcoming 2.0 release to prevent tab freezing and disconnection due to inactivity.

In the meantime, for a stable, long-term connection, consider using MQTTX CLI, which doesn't have this issue but lacks a GUI. Alternatively, enabling the desktop version's auto-reconnect feature may help by immediately attempting to reconnect after disconnection.

Thanks for the feedback.

Already have the auto-reconnect enabled, but sometimes it will give-up the reconnections attempt, but need to check if it is any issue with the broker (NanoMQ).

Will wait for release of v2.0 to check if it is OK.
