1：如下条件都要满足才可以进入SLEEP

  1.1:

emAfForceEndDeviceToStayAwake=TURE;   不能SLEEP

1.2：

   如果emAfStayAwakeWhenNotJoined=1，则只有设备加入网络了才能睡觉

1.3：串口BUF中要没有数据才能睡觉

1.4这里面的任务的(emberAfGetCurrentSleepControlCallback() != EMBER_AF_STAY_AWAKE);

#define EMBER_AF_GENERATED_EVENT_CONTEXT { 0x1, 0x3, false, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfIdentifyClusterServerTickCallbackControl1}, \
{ 0x1, 0x19, true, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfOtaBootloadClusterClientTickCallbackControl1}, \
{ 0x2, 0x3, false, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfIdentifyClusterServerTickCallbackControl2}, \
{ 0x3, 0x3, false, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfIdentifyClusterServerTickCallbackControl3}, \
{ 0x4, 0x3, false, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfIdentifyClusterServerTickCallbackControl4}, \
{ 0x4, 0x19, true, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfOtaBootloadClusterClientTickCallbackControl4}

开发人员可以使用下面这个函数来控制要不要进入睡眠

void emberAfForceEndDeviceToStayAwake(bool stayAwake)
