I am working on an environmental sensor for a project collecting data (temp, humidity, PM2.5, CO2, etc.) usinng an Arduino Giga R1 Wifi, and publishing it to HiveMQ. The sensor had been publishing data every 10 seconds or so for 2-3 weeks with no problem. Recently the publish function has stopped working with no changes to the code. When I start up the arduino it connects to the broker, runs through the setup no problem, but when it goes to publish only the first 5-6 sub-topics publish, then it continues through the code. After the first cycle nothing publishes, but the rest of the code keeps running. I am well below the 10Gb data limit as I have published less than 37Mb to date.
While trouble shooting I switched the broker to test.mosquito and it publishes no problem.
I ave also adapted the code to run on an Arduino Uno Rev 4 Wifi, and that publishes to HiveMQ no problem.
So the issue seems to be with this particular board (the Arduino Giga)publishing to Hive MQ. Again, this board ran fine for 2-3 weeks, then just wont publish to my Hive MQ cluster anymore.
Hello @apleo, and a hearty welcome to the HiveMQ Community! Your interest in MQTT and the HiveMQ broker is much appreciated. We’re always happy to see new users like you.
It sounds like there might be an issue with the HiveMQ Cloud Serverless service. To further investigate this, could you please create an issue in the HiveMQ Cloud Support portal? You can do so at the following link: HiveMQ Cloud Support Portal. When creating the issue, please make sure to include the hostname of the problematic cluster and any other relevant details.
