Other Parts Discussed in Thread: Z-STACK

I want to control light in location(sample)

may I  use this code? 

static void processMSGCmd( afIncomingMSGPacket_t *pkt )
{
switch ( pkt->clusterId )
{
case SAMPLE_APP_ON_OFF_ID:
switch ( pkt->cmd.Data[0] )
{
case SAMPLE_APP_OFF:
HalLedSet( HAL_LED_3, HAL_LED_MODE_OFF );
break;

case SAMPLE_APP_TOGGLE:
HalLedSet( HAL_LED_3, HAL_LED_MODE_TOGGLE );
break;

case SAMPLE_APP_ON:
HalLedSet( HAL_LED_3, HAL_LED_MODE_ON );
break;
}
break;

default:
break;
}
}
