Cannot wake up after enter extened_sleep

HI DAteam

i set

---------------------------------------------------------------------------------------------------------------

hw_wkup_init(NULL);
hw_wkup_set_debounce_time(32);
hw_wkup_configure_pin(HW_GPIO_PORT_4, HW_GPIO_PIN_1, true,HW_WKUP_PIN_STATE_HIGH);
hw_wkup_register_interrupt(wkup_handler, configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY);

---------------------------------------------------------------------------------------------------------------

and the wkup_handler is

----------------------------------------------------------------------------------------------------------------

空白wkup_handler (void) {
pm_system_wake_up();
hw_wkup_reset_interrupt();
}
----------------------------------------------------------------------------------------------------------------

i use "pm_set_sleep_mode(pm_mode_extened_sleep)" enter sleep mode ,

then i can'not wake up !

Is it wrong with me?

if i set wkup_handler as follows:

-----------------------------------------------------------------------------------------------------

空白wkup_handler (void) {
hw_cpm_reboot_system();
}

------------------------------------------------------------------------------------------------------

then i can "wake up",But this is not a real wake up. And this will cause the Bluetooth connection to be interrupted while sleeping.

I need to wake up the device normally. Can you give me some advice? thanks very much!
