mqttSetSubscrib()函数<br />
<br><br />
需要调用<code style="color: #E87E05">#include <Microduino_Ai.h></code>头文件。<br />
<br><br />
<p style="color: #E87E05;font-size:135%">参数</p><br />
char* sub:订阅ID，为字符指针<br />
<p style="color: #E87E05;font-size:135%">实例</p><br />
首先声明topic，格式保持原样，斜杠后为设备ID<br />
<source lang="cpp"><br />
#define SUBSCRIBTOPIC "ca/58f881ae42c66e00013cf445"<br />
#define SUBSCRIBTOPICP "cp/58f881ae42c66e00013cf445"<br />
</source><br />
之后使用该函数订阅topic<br />
<source lang="cpp"><br />
if (mAi.mqttSetSubscrib(SUBSCRIBTOPIC)) {<br />
Serial.println(F("set mqtt subscrib ca topic OK!"));<br />
} else {<br />
Serial.println(F("set mqtt subscrib ca topic failed"));<br />
}<br />
<br />
if (mAi.mqttSetSubscrib(SUBSCRIBTOPICP)) {<br />
Serial.println(F("set mqtt subscrib cp topic OK!"));<br />
} else {<br />
Serial.println(F("set mqtt subscrib cp topic failed"));<br />
}<br />
