我现在使用2541的demo工程，当设为省电模式时
按键后30秒设备可查找
我们需要的是没有按键的省电模式，比如advertise 100ms，休眠1秒
我做如下的初始化：
uint8 initial_advertising_enable = TRUE;
// By setting this to zero, the device will go into the waiting state after
// being discoverable for 30.72 second, and will not being advertising again
// until the enabler is set back to TRUE
uint16 gapRole_AdvertOffTime = 1000;
...(其他初始化使用默认)
// Set fast advertising interval for user-initiated connections （仿照按键响应代码）
GAP_SetParamValue( TGAP_GEN_DISC_ADV_INT_MIN, DEFAULT_FAST_ADV_INTERVAL );
GAP_SetParamValue( TGAP_GEN_DISC_ADV_INT_MAX, DEFAULT_FAST_ADV_INTERVAL );
GAP_SetParamValue( TGAP_GEN_DISC_ADV_MIN, 100 );
修改了osal_pwrmgr_powerconserve函数使上电后一分钟才能休眠，让advertise有机会执行：
void osal_pwrmgr_powerconserve( void )
{
uint32 next;
halIntState_t intState;
// Should we even look into power conservation
if ( pwrmgr_attribute.pwrmgr_device != PWRMGR_ALWAYS_ON && osal_GetSystemClock()>60000)
{
...
现在的问题是，休眠后无法自动唤醒发advertise，请问应该如何解决？
