Question

我正在与Arduino Uno和ESP8266合作。

我将ESP8266连接到Arduino Uno，并下载了ESP8266库（https://github.com/Diaoul/arduino-ESP8266）..

＆＃39; joinAP＆＃39;没事，连接＆＃39;也没关系。

但问题是http请求。

＆＃34; getStatus（wifi.send（＆＃34; GET / HTTP / 1.0 \ r \ n \ r \ n \ n＆＃34;））＆＃34;在设置代码中始终显示我＆＃39; TIMEOUT＆＃39;。

以下是我的代码。

请保存我的代码..

#include <SoftwareSerial.h>
#include "ESP8266.h"

#define SSID "SSID"
#define PASS "PASS"
#define DST_IP "www.google.com"

SoftwareSerial esp8266Serial = SoftwareSerial(2, 3);
ESP8266 wifi = ESP8266(esp8266Serial);

void setup()
{
Serial.begin(9600);

// ESP8266
esp8266Serial.begin(9600);
wifi.begin();
wifi.setTimeout(10);

Serial.print(getStatus(wifi.getVersion(version, 16)));

Serial.println(getStatus(wifi.setMode(ESP8266_WIFI_STATION )));
}

Serial.println("already ESP8266_WIFI_STATION mode");

如何用ESP8266修复Arduino中的超时？
