SIM800 send buffer

[frohr]

Hey all,
does anybody have experience with SIM800L module and sending data? I need send 4kB every 1 hour or every request.
Now I am able send two values every 10 seconds to MySQL and draw data with Google charts to have trend.
But I need send array 4096 values and draw chart at one time.
Any idea how to do it?

My code now:

  Serial.print("Set Phone Function... ");
  Serial.println(http.setPhoneFunc(1));
  Serial.print("is Module Registered to Network?... ");
  Serial.println(http.isRegistered());
  Serial.print("Signal Quality... ");
  Serial.println(http.signalQuality());
  Serial.print("Operator Name... ");
  Serial.println(http.operatorNameFromSim());
  Serial.print("Connect GPRS... ");
  Serial.println(http.connect());
  Serial.print("Get IP Address... ");
  Serial.println(http.getIP());
  Serial.println(http.get("myserver/write_data.php?data1=10&data2=20"));

Thanks a lot!
Michal

The character limit for a single SMS message is 160 characters. However, most modern phones and networks support concatenation; they segment and rebuild messages up to 1600 characters. Messages not using GSM-7 encoding are limited to 70 characters.
