在系统崩溃中连接的ProSualt期间PowerTown外围设备

亲爱的对话框，
I try to reduce the power of my system，when the phone connect to the dialog14580，i didn‘t call periph_init() until data transfer ble -> uart, I call user_wakeup_hold_set() and start data transfer, after a time, the timer callback will call to restore_sleep_mode, here the problem coming when device go to sleep, system crash ！！

void user_wakeup_hold_set（void）
{
if（wakeup_hold_timer_used == 0）
{
wakeup_hold_timer_used = app_easy_timer（user_wakeup_hold_time，wakeup_hold_timer_cb_handler）;

periph_init（）;
ARCH_FORCE_ACTIVE_MODE（）;

ARCH_PRINTF（“唤醒持有\ n”）;
}
别的
{
wakeup_hold_timer_used = app_easy_timer_modify（wakeup_hold_timer_used，user_wakeup_hold_time）;
ARCH_PRINTF（“唤醒保留重置\ n”）;
}
}

静态void wakeup_hold_timer_cb_handler（void）
{
ARCH_RESTORE_SLEEP_MODE（）;
wakeup_hold_timer_used = 0;
ARCH_PRINTF（“唤醒保持清除\ n”）;
}

我不知道搞清楚，请帮帮我，谢谢你很糊精！
