How Do I use sleep Timer to awake CC2530

Hi Everyone,

My CC2530 enter power mode 2.

I use sleep timer to awake CC2530.

But it doesn't work.

My program is shown as follows.

void main(void)

{

uint8_t sendmsg[]=
{
0X41, 0X42, 0X43, 0X44, 0X45,
};

CLKCONCMD |= 0x88; //Enable 32Khz RCOSC

SetSleepTime(4); // Setting sleep timer is 4 sec
SleepTimerInit();

SLEEPCMD |= 0x06; // Setting power mode 2
PCON |= 0x01; // Enable power mode

SMPL_Send(LinkID, sendmsg, strlen(sendmsg));

}

static void SetSleepTime(unsigned short sec)
{
unsigned long sleeptime = 0;

/* read sleep timer value*/
sleeptime |= ST0;
sleeptime |= (unsigned long)ST1 << 8;
sleeptime |= (unsigned long)ST2 << 16;

sleeptime += ((unsigned long)sec * (unsigned long)32753);

/* set sleep timer */
while((STLOAD & 0x01) == 0); // wait before ST0. STLOAD.LDRDY is 0 during the load
ST2 = (unsigned char)(sleeptime >> 16);
ST1 = (unsigned char)(sleeptime >> 8);
ST0 = (unsigned char) sleeptime;
}

static void SleepTimerInit(void)
{
   // Enable sleep timer interrupt
   IRCON |= 0x80;
   IEN0 |= 0x20;
   EA = 1; // Enable global interrupt
}

I couldn't saw that the sendmessage was sent.

Can please someone help me out with this...

I would be very grateful.

Thanks,

Jack
