It is designed to facilitate developers to quickly deploy industrial-level LoRaWAN and IoT solutions. It helps users to turn the idea into a practical application and make the Internet of Things a reality. It is easy to create and connect your things everywhere.

325 +
326 +After see LoRaWAN Online, walk around and the APP will keep sending location info to LoRaWAN server and then to the Node Red.
