http GET don't work after sleep #9
Description
Im scratching my head for few days with this one. When i do GET request it works but when I put module to sleep and then do request it doesn't.
Here is my code:
#include <BareBoneSim800.h>
BareBoneSim800 sim800("internet.bob.si"); //to declare the library with an APN
const char resource[] = "m2msupport.net/m2msupport/test.php";
const int port = 80;
void setup() {
Serial.begin(9600);
sim800.begin();
while(!Serial);
Serial.println("Testing GSM module For GPRS Connectivity");
delay(8000); // this delay is necessary, it helps the device to be ready and connect to a network
Serial.println("Should be ready by now");
bool deviceAttached = sim800.isAttached();
if (deviceAttached)
Serial.println("Device is Attached");
else
Serial.println("Not Attached");
}
void loop() {
sim800.disableSleep();
sim800.setFullMode();
// Connecting the the GPRS APN Network
Serial.println(" Connecting to APN");
bool netConnect = sim800.gprsConnect();
if(netConnect)
Serial.println("Connected to Network");
else
Serial.println("An Error Occured");
if(netConnect)
{
Serial.println("Making HTTP Get Request");
String result = sim800.sendHTTPData(resource);
Serial.println("Received Info: ");
Serial.println(result);
}
sim800.closeHTTP(); // disconnect from server
sim800.gprsDisconnect();
bool sleepActivated = sim800.enterSleepMode();
if(sleepActivated)
{
Serial.println("zzzzZZZZZZzzzzz");
delay(5000);
}
}
this is debug for first request
