hello, i need your help
i wanna send .txt file from third party SD card module to ftp server.
i use 3G shield sim5216...
i followed example from cooking hack http://www.cooking-hacks.com/documentation/tutorials/arduino-3g-gprs-gsm-gps#step13
in cooking hack case, their use 3g shield with built in sd card module,
but i use external sd card module
and here is my code :
int led = 13;
int onModulePin = 2; //
int x = 0;
int y = 0;
int z=0;
boolean isConnected=false;
boolean isUploaded=false;
boolean isOn=false;
char name[20];
char data[1024];
long previous;
// cek koneksi
int chckCREG()
{
Serial.println("chckCREG");
// if 1,0 or 5,0 or ERROR
if((data[x-1]=='1'&&data[x-2]==','&&data[x-3]=='0')||(data[x-1]=='5'&&data[x-2]==','&&data[x-3]=='0')||(data[x-1]=='0'&&data[x-2]==','&&data[x-3]=='0')||(data[x-1]=='R'&&data[x-2]=='O'&&data[x-3]=='R'))
{
return 1;
