我正在处理一个在线找到的 Arduino 项目,但我在配置 wifi 模块时遇到了问题。我使用的是 Az Delivery ESP8266 wifi 模块,我编写的代码如下
#define SSID "SSID" //replace XXXXX by your router SSID
#define PASS "PSW!" //replace YYYYY by your router password
//communication with wifi module
monitor.flush();
monitor.println("AT");
delay(2000);
if(monitor.find("OK")){
Serial.println("Communication with ESP8266 module: OK");
}
else {
Serial.println("ESP8266 module ERROR");
}
//connect wifi router
connectWiFi();
Serial.print("Sampling (");
Serial.print(sampletime_ms/1000);
Serial.println("s)...");
//initialize timer
starttime = millis();
}
boolean connectWiFi(){
Serial.println("Connecting wi-fi...");
String cmd ="AT+CWMODE=1";
monitor.println(cmd);
delay(2000);
monitor.flush(); //clear buffer
cmd="AT+CWJAP=\"";
cmd+=SSID;
cmd+="\",\"";
cmd+=PASS;
cmd+="\"";
monitor.println(cmd);
delay(5000);
if(monitor.find("OK")){
Serial.println("Connection succeeded!");
return true;
}else{
Serial.println("Connection failed!");
return false;
}
Serial.println();
}
我在运行时没有收到错误,并且代码可以编译,但是当我打开串行监视器时,我看到 wifi 模块在第一个周期失败并打印模块错误。
我错过了什么?
