我試圖從Arduino發佈一些手動數據到服務器。我正在使用SIM 900進行數據連接..數據沒有到達服務器.. SIM卡已經初始化,沒有錯誤,但數據沒有發佈到服務器..請幫我解決這個問題..代碼是下面..使用SIM卡發送數據使用HTTP請求900
#include<SoftwareSerial.h>
SoftwareSerial client(2,3);
String testReading="{ \"testID\" : 1, \"testLevel\" : 1, }";
void setup()
{
Serial.begin(9600);
client.begin(9600);
delay(1000);
if(client.available())
{
Serial.print("Connected");
}
else
{
Serial.print("Not Connected");
}
checkSignal();
connectGPRS();
postData();
delay(1000);
}
void loop()
{
if(client.available())

checkSignal();
connectGPRS();
postData();
delay(1000);

delay(1000);
ShowSerialData();
client.println("AT+SAPBR=3,1,\"CONTYPE\",\"GPRS\"");
