WiseAgentLite is a lite agent library to adapt to a poor performance platform. it is seperated into two layers, RMM layer and MQTT layer. The RMM layer includes the general protocol with RMM server. The MQTT layer is a abstract layer, it is a interface of MQTT on different platform.

Architecture

WiseAgentLite only includes the blue block. The MQTT interface must be ported to adapt to different MCU.

Functions

RMM Layer


void WiseAgent_Init(char *ip, unsigned char *mac, char *parentId, char *deviceName);

Description

  • This function initializes the basic information.

Parameters

  • ip [POINTER]
    • the ip address of this device.
  • mac [POINTER]
    • the mac hex table of this device.
  • parentId [POINTER]
    • the parentId of this device.
  • deviceName [POINTER]
    • the default device name of this device.

Return Values

  • None


int WiseAgent_Open(char *server_url, int port, char *username, char *password);

Description

  • This function initializes MQTT connection and sends initial messages to RMM. You must call this function before using others.
