Drawing upon the success of our previous ‘Ask Me Anything About MQTT’ webinar and on popular demand, we started a webinar series under the same name. In this March 2022 edition, our MQTT experts answered questions around MQTT 3, MQTT 5, MQTT Sparkplug, OPC-UA, AMPQ, ISA 95, and IoT architecture.

Jens Deters, Head of Professional Services at HiveMQ and Florian Raschbichler, Head of Support at HiveMQ, personally answered questions live during the webinar.

Feel free to ask questions on the HiveMQ Community Forum.
