ZigBee各种传输方式的稳定性对比

1&2、终端是否收到，可以通过MAC ACK判断：

#define MAC_ACK_WAIT_DURATION             0x40  /* The maximum number of symbols to wait for an acknowledgment frame */

3、会，用户可以设置hold数据的时间及数量：

// 1-255 (0 -> 256) X RTG_TIMER_INTERVAL
// A known shortcoming is that when a message is enqueued as "hold" for a
// sleeping device, the timer tick may have counted down to 1, so that msg
// will not be held as long as expected. If NWK_INDIRECT_MSG_TIMEOUT is set to 1
// the hold time will vary randomly from 0 - CNT_RTG_TIMER ticks.
// So the hold time will vary within this interval:
// { (NWK_INDIRECT_MSG_TIMEOUT-1)*CNT_RTG_TIMER,
//                                    NWK_INDIRECT_MSG_TIMEOUT*CNT_RTG_TIMER }
#define NWK_INDIRECT_CNT_RTG_TMR    1
// To hold msg for sleeping end devices for 30 secs:
// #define CNT_RTG_TIMER            1
// #define NWK_INDIRECT_MSG_TIMEOUT 30
// To hold msg for sleeping end devices for 30 mins:
// #define CNT_RTG_TIMER            60
// #define NWK_INDIRECT_MSG_TIMEOUT 30
// To hold msg for sleeping end devices for 30 days:
// #define CNT_RTG_TIMER            60
// #define NWK_INDIRECT_MSG_TIMEOUT (30 * 24 * 60)
// Maximum msgs to hold per associated device.
#define NWK_INDIRECT_MSG_MAX_PER    3
// Maximum total msgs to hold for all associated devices.
#define NWK_INDIRECT_MSG_MAX_ALL    \
                            (NWK_MAX_DATABUFS_TOTAL - NWK_INDIRECT_MSG_MAX_PER)

zcl_SendReportCmd里會使能AF_ACK_REQUEST，如果沒收到AF_ACK_REQUEST，就會重发
