Static / programmable whitelist

[Bjarke]

Hi,

Is it possible to add a static bluetooth address to the whitelist?

I am using SDK 14.2.0, device is nrf52832 + peer manager.

Hi,

Whitelist can be used both by peripheral (to filter which centrals can connect) and by central (to filter what peripherals to connect to.) I assume that you need this for a peripheral.

If you use the Advertising Module then it is your responsibility to provide a whitelist on the BLE_ADV_EVT_WHITELIST_REQUEST event.

You may then choose to fetch a whitelist from peer manager using pm_whitelist_get(), as is done for instance in the HID Mouse Application example.

Or, in your case, you may make a whitelist manually using any Bluetooth addresses that you would like. The whitelist is an array of ble_gap_addr_t structures and an array of ble_gap_irk_t structures. (The IRK structure is only needed for resolvable addresses, not for static ones.)

In any case you must reply to the whitelist request event with a call to ble_advertising_whitelist_reply(), where you provide the whitelist.

Hi,

I have been looking at ble_advertising.c, and can see that for Softdevice >2, the adresses are not used in the ble_advertising_whitelist_reply(...

from ble_advertising.c:

uint32_t ble_advertising_whitelist_reply(ble_advertising_t * const p_advertising,
                                         ble_gap_addr_t    const * p_gap_addrs,
                                         uint32_t               addr_cnt,
                                         ble_gap_irk_t  const * p_gap_irks,
                                         uint32_t               irk_cnt)
{
    if (!p_advertising->whitelist_reply_expected)
    {
        return NRF_ERROR_INVALID_STATE;
    }

    p_advertising->whitelist_reply_expected = false;

    #if (NRF_SD_BLE_API_VERSION <= 2)

        p_advertising->whitelist.addr_count = addr_cnt;
        p_advertising->whitelist.irk_count  = irk_cnt;

        for (uint32_t i = 0; i < addr_cnt; i++)
        {
            *p_advertising->whitelist.pp_addrs[i] = p_gap_addrs[i];
        }

        for (uint32_t i = 0; i < irk_cnt; i++)
        {
            *p_advertising->whitelist.pp_irks[i] = p_gap_irks[i];
        }

    #else

        p_advertising->whitelist_in_use = ((addr_cnt > 0) || (irk_cnt > 0));

    #endif

    return NRF_SUCCESS;
}

Any ideas?

Regards
