Arduino GMS Shield获取请求

Question

我正在建立一个气象站，通过GET请求将数据发送到网络服务器。我想知道你们是否可以查看我的代码并帮助我。我浏览了整个互联网，找不到什么问题。我正在使用arduino mega，arduino / telefonica gsm盾牌和EE SIM卡。非常感谢你！

#include <GSM.h>

GSM gsmAccess;
GPRS gprs;
GSMClient client;

const boolean gprsCheck = true;

char server[] = "";

int value = 112358132134;

void setup(){

  Serial.begin(19200);

  if(gprsCheck) {

    boolean notCon = true;

    Serial.println("Establishing connection...");

    while(notCon) {

      if((gsmAccess.begin("") == GSM_READY) & (gprs.attachGPRS("everywhere","eesecure","secure") == GPRS_READY)) {

        notCon = false;

        Serial.println("GPRS connection successful.");
        Serial.println("");
      }

      else {

        Serial.println("GPRS connection failed. Trying again.");
        Serial.println("");

        delay(1000);
      }
    }
  }

  if(!client.available() && !client.connected()) {

    client.stop();
  }

  if (client.connect(server, 80)) {

    Serial.println("Connection successful.");

    client.print( "GET /add.php?");
    client.print("value=");
    client.print(value);
    client.print(" HTTP/1.1\n");
    client.print("Host: ");
    client.print(server); 
    client.print("\nConnection: close\n\n");
    client.stop();
    client.stop();

    Serial.println("Data sent.");
  }

  else {

    Serial.println("Error.");
  }
}

void loop() {
}
