MQTT client stability ? - lgn@ltr@n - 05-10-2018 Hello, Now that I'm able to connect to google IOT core (MQTT), I observed another issue last night. Connection with token valid for 24 hours occurred somewhere in the afternoon. publish to google worked fine. subscription to google worked fine, I received config data. During the night, subscription stopped receiving data. I see in google that data was sent to GW all night long (once every 100 seconds). but it was no more received in the Mqttclient. No logs available, it's been 10 hours at least since first time data was no more received. I only can say the method callMqttEvent() was no more called. I restarted the application to recover. Are you aware of issues/instabilities in the subscribe on Ewon client ? Rgds Laurent RE: MQTT client stability ? - ntnunk - 05-10-2018 I have a number of eWONs running MQTT clients, though mine are pointed at AWS IoT Core, not Google. I have a number of them that have been running continuously for months and, for whatever it's worth, I haven't seen these instability issues. The client and the logging has been been very stable for me.
