What do LEDs 0 and 1 indicate in the ble_proximity sample app?

[Eliot Stock]

Here are some constants from main.c for the other LEDs, but what do LEDs 0 and 1 indicate? 0 seems to be on when advertising. 1 when connected? What about pairing/bonding state?

#define ALERT_LEVEL_MILD_LED_PIN_NO NRF6310_LED_2 /< Is on when we are in Mild Alert state. */ #define ALERT_LEVEL_HIGH_LED_PIN_NO NRF6310_LED_3 /< Is on when we are in High Alert state. */ #define ADV_INTERVAL_SLOW_LED_PIN_NO NRF6310_LED_4 /< Is on when we are doing slow advertising. */ #define PEER_SRV_DISC_LED_PIN_NO NRF6310_LED_5 /< Is on when the Immediate Alert Service has been discovered at the peer. */ #define ADV_WHITELIST_LED_PIN_NO NRF6310_LED_6 /**< Is on when we are doing advertising with whitelist. */

Hi Eliot,

as you say, LED 0 is set when advertising, and LED 1 is set when connected. There is no LED activity that indicates pairing state.

If you want main.c to handle bond-related events, you should implement the evt_handler provided in ble_bondmngr_init(). See bond_manager_init in main.c. For example:

static void bond_manager_event_handler(ble_bondmngr_evt_t * p_evt)
{
    switch (p_evt->evt_type)
    {
        case BLE_BONDMNGR_EVT_NEW_BOND:
            break;
        
        case BLE_BONDMNGR_EVT_CONN_TO_BONDED_MASTER:
            break;
        
        case BLE_BONDMNGR_EVT_ENCRYPTED:
            break;
        
        case BLE_BONDMNGR_EVT_AUTH_STATUS_UPDATED:
            break;
        
        case BLE_BONDMNGR_EVT_BOND_FLASH_FULL:
            break;
        
        default:
            // Unexpected event
            APP_ERROR_CHECK_BOOL(false);
            break;
    }
}
