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

  • Description: Agent Client sends the "Connect Info" to RMM Server for on-line notification.
  • Type: Info
  • Direction: Agent -> Server
  • Topic: /cagent/admin/<devID>/agentinfoack
  • QoS: 2
  • Retained: 0
  • Payload:
{
  "susiCommData": {
