NRF51822可以关闭睡眠模式吗

把這err_code註解掉就好
static void sleep_mode_enter(void)
{
    uint32_t err_code = bsp_indication_set(BSP_INDICATE_IDLE);
        ....

    // Go to system-off mode (this function will not return; wakeup will cause a reset).
    //err_code = sd_power_system_off();
    //APP_ERROR_CHECK(err_code);
}
