Overview

Introduction for "WISEAgent communication protocol". WISEAgent communication protocol is base on standard MQTT protocol. We also define Advantech IoT Topic and message in JSON format. Follow standard to design our [Sensor Format in JSON ]

Protocol

Connect

Agent Client sends the "Connect Info" to Server for on-line notification. Server would send "Get Capability" to get capability of this agent device and "Change AdvHeartBeat rate" to sync with System's sending rate.
