CC2531 Power mode 2 and wake up from RF

HI

I'm using CC2531 and programming it on "rf_modem" example.

I'm try to set chip in PM2, and wake up from RF signal.

I wonder PM2 can do that? If can what should I notice?

Here is my code to enter PM2:

void main(void){
  halBoardInit();
  halTimer32kIntEnable();
  
  halIntOn();
  IEN2 = 0x01;
  RFIRQM0 = 0x40;

  while(TRUE){
    halLedSet(1);
    
    if(mrfiLinkDataRdy()){
      mrfiLinkRecv(pRxData);
      if(pRxData[0] == 0x41){
        halLedSet(2);
        EnterPowerMode();
      }
      else{ 
        halLedClear(2);
      }
    }
  }
}

void EnterPowerMode(void){
    do{
      halLedClear(1);
      SLEEPCMD = 0x06;
      PCON = 0x01;
    }while(!mrfiLinkRecv(pRxData) == 0);
}

From now the chip can sleep when I send "A", but it can't wake up anymore.

I want it wake up when I send some message not even "A".

Thanks for any help.
