nRF5_SDK_15.3.0 cannot enter low power

[libailiang]

Hi 

When I use the nRF5_SDK_15.3.0, the nRF52832 cannot enter low power (about 900uA). The example is file ble_app_blinky. 

The main code is as following:

int main(void)
{
    // Initialize.
    log_init();
    leds_init();
    timers_init();
    buttons_init();
    power_management_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();

   // Start execution.
   NRF_LOG_INFO("Blinky example started.");
   advertising_start();

   // Enter main loop.
   for (;;)
   {
       idle_state_handle();
    }
}

Could you give me some advice. Thanks.
