Hi,
I am trying to send a SMS via a gsm modem(ADH8066) interfaced with an IRIS
mote. I have the GSM modem working with AT commands using hyper-terminal. I
also have the UART interface between the IRIS mote and the PC working with the
mote sending AT commands to the hyper-terminal. However now when I connect the
mote and the GSM modem, it does not work. I have checked the power supply for
GSM modem which seems fine. All the baud settings are also correct.
I am not sure what I could be missing..Could it be something to do with CTS,DTR
?Can anyone please advise me as to how I should progress? It would be of great
help.
Here is my code :
#include "printf.h"
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
{
enum {
UART_BUF_MAXLEN = 15
};
char* uartsendBuf1 = "AT\n\r";
char* uartsendBuf2 = "AT+CMGF=1\n\r";
char* uartsendBuf3 = "AT+CMGS=";
char* uartsendBuf4 = "+6590140252";
char* newline = "\n\r";
char* msg = "Hello";
uint8_t recevedByte;
uint8_t stage = 0;
uint8_t flag = 0;
uint8_t uartBuf[UART_BUF_MAXLEN];
/** Count of bytes read into #uartBuf during a reading. */
uint8_t uartBufCount;
event void Boot.booted() {
call UartInit.init();
call Timer.startPeriodic(3000);
call UartControl.start();
//call Timer.startPeriodic(2000);
}
event void Timer.fired() {
switch (stage) {
case 0:
call UartControl.start();
call UartStream.send(uartsendBuf1, 4);
break;
case 1:
call UartControl.start();
call UartStream.send(uartsendBuf2, 11); //at+cmgf=1
break;
case 2:
call UartControl.start();
call UartStream.send(uartsendBuf3, 8); // at+cmgs=
break;
case 3:
call UartControl.start();
call UartStream.send(0x22,1); // "
break;
case 4:
call UartControl.start();
call UartStream.send(uartsendBuf4,11); //phone number
break;
case 5:
call UartControl.start();
call UartStream.send(0x22,1); // " ""
break;
case 6:
call UartControl.start();
call UartStream.send(newline,2); //newline
break;
case 7:
call UartControl.start();
call UartStream.send(msg,5); //message
break;
case 8:
call UartControl.start();
call UartStream.send(0x1A, 1); //comtrol z
break;
}
}
async event void UartStream.sendDone( uint8_t* buf, uint16_t len, error_t
error )
{
call Leds.led2Toggle();
stage++;
if (stage > 8)
{
stage = 0;
}
call UartControl.stop();
}
async event void UartStream.receivedByte( uint8_t byte )
{
}
async event void UartStream.receiveDone( uint8_t* buf, uint16_t len, error_t
error )
{
}
}
