Hi,
I am trying to send a series of commands to the PC hyperterminal using UART
interface. Now when I send a single command it works fine. But when I send a
series of commands it stops working. I have tried to create delays after each
command but still it does not work. Can anyone tell me what I can possibly do?
Here is my code :
module GSMmodemC @safe()
{
uses interface Boot;
uses interface Init as UartInit;
uses interface StdControl as UartControl;
uses interface UartStream;
uses interface Leds;
uses interface Timer<TMilli>;
}
implementation
{
// COMMANDS TO BE SENT
char* uartsendBuf1 = "AT\n";
char* uartsendBuf2 = "AT+CMGF=1\n";
char* uartsendBuf3 = "AT+CMGS=";
char* uartsendBuf4 = "+6590140252";
char* output = "Hello";
char* input;
uint16_t inputlen;
uint8_t recevedByte;
event void Boot.booted() {
call UartInit.init();
call Timer.startPeriodic(3000);
call UartControl.start();
}
static void delay(uint32_t cycles)
{
while (--cycles > 0)
{
//nop();
}
}
event void Timer.fired() {
call UartControl.start();
call UartStream.send(uartsendBuf1, 3);
/*call Leds.led1Toggle(); // This part does
not work
delay(5000);
call UartControl.start();
call UartStream.send(uartsendBuf2, 10);
call Leds.led1Toggle();
delay(5000);
call UartControl.start();
call UartStream.send(uartsendBuf3, 8);
call Leds.led1Toggle();
delay(5000);
call UartControl.start();
call UartStream.send(uartsendBuf4, 11);
call Leds.led1Toggle();
delay(5000); */
}
async event void UartStream.sendDone( uint8_t* buf, uint16_t len, error_t
error )
{
call Leds.led0Toggle();
call UartStream.enableReceiveInterrupt();
}
async event void UartStream.receivedByte( uint8_t byte )
{
if( (char* )byte == "a")
{
call Leds.led1Toggle();
}
call Leds.led2Toggle();
recevedByte = byte;
call UartControl.stop();
}
async event void UartStream.receiveDone( uint8_t* buf, uint16_t len, error_t
error )
{
}
}
