I am student in university, new in MQTT, used MQTTlens and MQTT.fx as the client.
Used them to subscribe the public channel "1293177", the channel publish weather data frequently.
But, only got the first record immediately after subscribe, and no more.
If subscribe again, will got the same record again.
I follow the article at https://www.mathworks.com/help/thingspeak/troubleshoot-MQTT-subscribe.html and without mismatch.
Would you kindly help to figure out the problem is?
