在SDK 3.0.6中，我使用了一个按钮P23来启动系统。

void app_button_enable(void)
{
wkupct_register_callback(app_button_press_cb);

//if (!(GPIO_GetPinStatus(GPIO_BUTTON_PORT, GPIO_BUTTON_PIN))) //按钮是p23
wkupct_enable_irq(0x80000, 0, 1, 10);// P2_3，极性低，1 0 x40000 < br / >} < / p > < p > app_button_press_cb (void)我添加这个< br / >: < / p > < p > havekey_flag = 1; < / p > < p >如果(keytimescn> = 1) < br / > {< br / > keytimescn = 0; < br / > ke_timer_clear (SCAN_KEY_TIMER TASK_APP); < br / >} < / p > < p > keytimescn + +; < / p > < p >如果(PW_ON_OFF ! = 0) / /关机雕像权力在< br / > {< br / > / / ke_timer_init (); < / p > < p >GPIO_SetInactive (GPIO_TI_LED_PORT GPIO_TI_LED_PIN);//fot tip enter here the led is on

ke_timer_set(SOTF_PW_TIMER,TASK_APP,200);
}
else
{//搜索400MS_key

/* Default State handlers definition. */
EXTERN const struct ke_msg_handler app_default_state[] =
{
{SOTF_PW_TIMER, (ke_msg_func_t)poweron_soft_handler},
{GAPM_DEVICE_READY_IND, (ke_msg_func_t)gapm_device_ready_ind_handler},
.............
...........
}

In handler function:

int poweron_soft_handler(ke_msg_id_t const msgid,
void const *param,
ke_task_id_t const dest_id,
ke_task_id_t const src_id)
{
GPIO_SetInactive( GPIO_ALERT_LED_PORT, GPIO_ALERT_LED_PIN); //fot tip enter here. the led is on

{//soft poweron is the first prio
PW_ON_OFF =0;
been_tip_flag =0;

app_adv_start();

led_been_loop =TIP_LOOP_LEDON;
ke_timer_set(LEN_BEEN_TIP_TIMER,TASK_APP,1);
}

ke_timer_clear(SOTF_PW_TIMER,TASK_APP);

return (KE_MSG_CONSUMED);
}

I press key P23 to high one time last 6s { greater than in set here (ke_timer_set(SOTF_PW_TIMER,TASK_APP,200) 2s};
have enter the step:
GPIO_SetInactive(GPIO_TI_LED_PORT,GPIO_TI_LED_PIN); //fot tip enter here the led is on

but sometimes the step is not in:
GPIO_SetInactive( GPIO_ALERT_LED_PORT, GPIO_ALERT_LED_PIN); //fot tip enter here. the led is on

so the system is not poweron everytime.

my question is :
ke_timer_set(SOTF_PW_TIMER,TASK_APP,200); //only here call SOTF_PW_TIMER's function

but sometimes this function
poweron_soft_handler

is not call succeed.

why?

additional:
I have view this
http://support.dialog-semiconductor.com/faq/how-use-ketimer-during-wakeu...

but in 3.0.6 have no this MSG

struct create_new_timer_struct *req = KE_MSG_ALLOC(APP_CREATE_NEW_TIMER, TASK_APP, TASK_APP,

create_new_timer_struct);

create_new_timer_struct
and
APP_CREATE_NEW_TIMER
not included in my used SDK(3.0.6).
