How to connect HTTP web server to RN400

Contents

Thank you for purchasing the DEKIST RN400 product.

The Radionode RN400 model connects to the wide area network by wireless WiFi, and sends and receives data using the HTTP protocol on the web. Therefore, the web server developed by the customer can receive the measured data from the Radionode devices.

1. Radio Node Protocol V2
2. User-developed application (function to receive parameters passed to HTTP GET/POST methods and save them in the DB)
The above two applications must be installed on your web server to receive measurement data.

HTTP Radionode Protocol V2supports the ability to transmit measurement data intact to a web server developed by the customer.

CHECK-IN: It contains the function to periodically transmit device information (mac address, IP address, etc.) to the server when the device is turned on or in use, and also performs time synchronization with the server.
DATA-IN: It is responsible for periodically transmitting time information and sensor values of all channels to the server. The time information uses UNIX TimeStamp.

# RN400 and RN17X use the same protocol.
