I am not seeing a transition to BLE_ADV_EVT_SLOW. The transition I see goes from FAST to idle, without a transition to slow, from the configuration I don't expect to be in IDLE.
init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = app_data.advfast_interval;
init.config.ble_adv_fast_timeout = app_data.advfast_timeout;
init.config.ble_adv_slow_enabled = true;
init.config.ble_adv_slow_interval = app_data.advslow_interval;
init.config.ble_adv_slow_timeout = 0;
err_code = ble_advertising_init(&m_advertising, &init);
APP_ERROR_CHECK(err_code);
Have placed some debug logs to see the transitions:
static void on_adv_evt(ble_adv_evt_t ble_adv_evt)
{
switch (ble_adv_evt)
{
case BLE_ADV_EVT_FAST:
NRF_LOG_INFO( "BLE_ADV_EVT_FAST:" );
LEDS( if( m_led_on ) bsp_board_led_on(ADVERTISING_LED) );
break;
case BLE_ADV_EVT_SLOW:
NRF_LOG_INFO( "BLE_ADV_EVT_SLOW:" );
break;
case BLE_ADV_EVT_IDLE:
NRF_LOG_INFO( "BLE_ADV_EVT_IDLE:" );
advertising_start( false );
break;
default:
break;
}
}
The log output I receive show:
<info> app: BLE_ADV_EVT_FAST:
<info> app: BLE_ADV_EVT_IDLE:
<info> app: BLE_ADV_EVT_FAST:
<info> app: BLE_ADV_EVT_IDLE:

<info> app: BLE_ADV_EVT_IDLE:
<info> app: BLE_ADV_EVT_FAST:

This is with a S140 release of the SDK.
