direct advertising with whitelist

[armin]

Hi

I want to connect to only a single master device by s110. I used the example parameter setting from "ble_app_hids_keyboard" for gap_params_init, advertising_init and finally called err_code = ble_advertising_start(BLE_ADV_MODE_FAST);

Here my adervitsing_init function:

define APP_ADV_FAST_INTERVAL 0x0028
define APP_ADV_SLOW_INTERVAL 0x0C80
APP_ADV_FAST_TIMEOUT 30
APP_ADV_SLOW_TIMEOUT 180

    uint32_t       err_code;
    uint8_t        adv_flags;
    ble_advdata_t  advdata;

    // Build and set advertising data
    memset(&advdata, 0, sizeof(advdata));

    adv_flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
    advdata.name_type = BLE_ADVDATA_FULL_NAME;
    advdata.include_appearance = true;
    advdata.flags = adv_flags;
    advdata.uuids_complete.uuid_cnt = 1;
    advdata.uuids_complete.p_uuids = pAdvUuid;

    ble_adv_modes_config_t options =
    {
        BLE_ADV_WHITELIST_ENABLED,
        BLE_ADV_DIRECTED_ENABLED,
        BLE_ADV_DIRECTED_SLOW_DISABLED, 0,0,
        BLE_ADV_FAST_ENABLED, APP_ADV_FAST_INTERVAL, APP_ADV_FAST_TIMEOUT,
        BLE_ADV_SLOW_ENABLED, APP_ADV_SLOW_INTERVAL, APP_ADV_SLOW_TIMEOUT
    };

    err_code = ble_advertising_init(&advdata, NULL, &options, OnAdvertiseEvent, ble_advertising_error_handler);

unfortunately, when I call the ble_advertising_start(BLE_ADV_MODE_FAST) it returns with NRF_ERROR_INVALID_PARAM.

Do you have an idea what it could be? The whitelist is requested by "BLE_ADV_EVT_WHITELIST_REQUEST" and successful created...

Thanks, BR Armin

it is called with this parameters (line 293-303, ble_advertising.c): adv_params.fp = BLE_GAP_ADV_FP_FILTER_CONNREQ;

adv_params.p_whitelist = &m_whitelist;

m_advdata.flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;

err_code = ble_advdata_set(&m_advdata, NULL);

if(err_code != NRF_SUCCESS)

{ return err_code; }

m_adv_evt = BLE_ADV_EVT_FAST_WHITELIST;

LOG("[ADV]: Starting fast advertisement with whitelist.\r\n"); --> where "ble_advdata_set" is executed successful

What do you put inside the whitelist? What is in it?

[armin]

ble_gap_whitelist_t whitelist;

ble_gap_addr_t * p_whitelist_addr[WHITELIST_ADDR_MAX_COUNT];

ble_gap_irk_t * p_whitelist_irk[WHITELIST_IRK_MAX_COUNT];

whitelist.addr_count = WHITELIST_ADDR_MAX_COUNT;

whitelist.irk_count = WHITELIST_IRK_MAX_COUNT;

whitelist.pp_addrs = p_whitelist_addr;

whitelist.pp_irks = p_whitelist_irk;

err_code = dm_whitelist_create(&mAppHandle, &whitelist);

err_code = ble_advertising_whitelist_reply(&whitelist);

break; do I have to set any address to it? or is the whiteliste after setting up managed handled by the s110?

[Petter Myhre]

Looks correct. But I meant if you could check what the contents of whitelist that is created. What address(es) and IRK(s) does it have in it? I can't also test your project here if you like, if you upload the complete project and tell me which SoftDevice and SDK version you are using.

[armin]

The whitelist has following params: addr_type = -26

addr_count = 1

irk = a value of 16 bytes

irk_count = 0 (..probably this is strange)

The size of the whitelist and irk is set to 1! ..i can't send you the entire code, since we do not have a non-disclosure agreement.
