这个不好说，代码看不到没法分析。
zigbee定位，让网关在一定时间内收不到数据包，就驱动网关的蜂鸣器响。
下面是网关主要程序：
//系统上电后，执行ZMain.c的int main()函数实现硬件的初始化，包括osal_int_disable( INTS_ALL );初始化板上硬件设置。。。当完成上述初始化时，执行osal_start_system()开始运行OSAL系统。（如下）
ZSEG int main( void )
{
// Turn off interrupts
osal_int_disable( INTS_ALL );
// Initialize HAL
HAL_BOARD_INIT();
// Make sure supply voltage is high enough to run
zmain_vdd_check();
// Initialize stack memory
zmain_ram_init();
// Initialize board I/O
InitBoard( OB_COLD );
// Initialze HAL drivers
HalDriverInit();
// Initialize NV System
osal_nv_init( NULL );
// Determine the extended address
zmain_ext_addr();
// Initialize basic NV items
zgInit();
// Initialize the MAC
ZMacInit();
#ifndef NONWK
// Since the AF isn't a task, call it's initialization routine
afInit();
#endif
#ifdef LCD_SUPPORTED
HalLcdInit();
#endif
// Initialize the operating system
osal_init_system();
// Allow interrupts
osal_int_enable( INTS_ALL );
// Final board initialization
InitBoard( OB_READY );
//HalLcdInit();
// Display information about this device
zmain_dev_info();
/* Display the device info on the LCD */
#ifdef LCD_SUPPORTED
zmain_lcd_init();
#endif
osal_start_system(); // No Return from here
} // main()
//osal_start_system()一旦执行，就不再返回上面的main（）函数。
//之后就进入下面的uint SampleApp_ProcessEvent(uint8 task_id,uint16 events)，判断收到的数据包，是什么事件，该函数如下：
uint16 SampleApp_ProcessEvent( uint8 task_id, uint16 events )
{
if ( events & SYS_EVENT_MSG )
{
afIncomingMSGPacket_t *MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive(
SampleApp_TaskID );
while ( MSGpkt != NULL )
{
switch ( MSGpkt->hdr.event )
{
case KEY_CHANGE:
handleKeys( ((keyChange_t *)MSGpkt)->state, ((keyChange_t *)MSGpkt)->keys );
break;
case AF_DATA_CONFIRM_CMD:
#if !defined( RTR_NWK )
{
// This message is received as a confirmation of a data packet sent.
// The status is of ZStatus_t type [defined in ZComDef.h]
afDataConfirm_t *afDataConfirm = (afDataConfirm_t *)MSGpkt;
/* No ACK from the MAC layer implies that mobile device is out of
* range of most recent parent. Therefore, begin an orphan scan
* to try to find a former parent.
* NOTE: To get the fastest action in the process of finding a new
* parent, set the MAX_JOIN_ATTEMPTS in ZDApp.c to 1.
*/
if ( afDataConfirm->hdr.status == ZMacNoACK )
{
SampleApp_NoACK();
}
// Some other error -- Do something.
else
{
}
}
#endif
break;
case AF_INCOMING_MSG_CMD:
processMSGCmd( MSGpkt );
break;
case ZDO_STATE_CHANGE:
#if defined( POWER_SAVING )
if ( rejoinPending )
{
rejoinPending = FALSE;
// Ok to resume power saving ops.
SampleApp_Sleep( TRUE );
}
#endif
break;
default:
break;
}
osal_msg_deallocate( (uint8 *)MSGpkt );
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );
}
// Return unprocessed events.
return ( events ^ SYS_EVENT_MSG );
}
return 0; // Discard unknown eve
}
现在就是加上逻辑功能没实现，帮帮忙。
