Wie öffne ich eine Webseite mit arduino und sim900 Modul Ich bin im Begriff, eine Webseite mit GSM SIM 900 Modul zu öffnen Ich habe versucht mit diesem Code Ich bin nicht vertraut mit den AT-Befehle, so dass dieser Code nur angezeigt wird ok als Antwort auf den Code im seriellen Monitor und es öffnet die Seite nicht so können Sie mir bitte helfen!Öffnen einer Webseite mit sim900
#include <SoftwareSerial.h>
SoftwareSerial SIM900(2, 3); // configure software serial port
void setup() {
SIM900.begin(19200);
SIM900power();
Serial.begin(19200);
Serial.print("power up");
delay(20000);
SIM900.println("AT+CSQ"); // Signal quality check
delay(100);
ShowSerialData();// this code is to show the data from gprs shield, in order to easily see the process of how the gprs shield submit a http request, and the following is for this purpose too.
SIM900.println("AT+CGATT?"); //Attach or Detach from GPRS Support
delay(100);
ShowSerialData();
SIM900.println("AT+SAPBR=3,1,\"CONTYPE\",\"GPRS\"");//setting the SAPBR, the connection type is using gprs
delay(1000);
ShowSerialData();
SIM900.println("AT+SAPBR=3,1,\"APN\",\"etisalat\"");//setting the APN, Access point name string
delay(4000)
ShowSerialData();
SIM900.println("AT+SAPBR=1,1");//setting the SAPBR
delay(2000);
ShowSerialData();
SIM900.println("AT+HTTPINIT"); //init the HTTP request
delay(2000);
ShowSerialData(); SIM900.println("AT+CIPSTART=\"TCP\",\"http://http://www.google.com\",\"80\"");
delay(1000);
ShowSerialData();
SIM900.println("AT+CIPSHUT"); //init the HTTP request
delay(2000);
ShowSerialData();
SIM900.println("AT+HTTPACTION=0");//submit the request
delay(10000);//the delay is very important, the delay time is base on the return from the website, if the return datas are very large, the time required longer.
while(!SIM900.available());
ShowSerialData();
SIM900.println("AT+HTTPREAD");// read the data from the website you access
delay(300);
ShowSerialData();
SIM900.println("");
delay(100);
}
void SIM900power()
// software equivalent of pressing the GSM shield "power" button
{
digitalWrite(9, HIGH);
