Extended Advertising on NRF52832

[NordJus]

Hi

Using SD Version 6.1.1 and NRF Version 15.3.0.

Using the following advertising params I can set non-extended advertising

ble_gap_adv_params_t advertisingParameters;

advertisingParameters.properties.type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED; // GAP Advertising type

using  

sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &advertisingParams);

As soon I change to

advertisingParameters.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_CONNECTABLE_NONSCANNABLE_UNDIRECTED

I get an error NRF_ERROR_INVALID_PARAM from the Softdevice is there a step I am missing here to use Bluetooth 5

There's more to the initialization function. More specifically you are probably calling sd_ble_gap_adv_set_configure() in the end to configure the advertising paramters.

Anyways, here's an example I tested with here, and is working with extended advertising:

static void extended_adv_init(void)
{
    memset(&m_adv_params, 0, sizeof(m_adv_params));
    //m_adv_params.properties.type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED;
    m_adv_params.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_CONNECTABLE_NONSCANNABLE_UNDIRECTED;
    m_adv_params.p_peer_addr     = NULL;
    m_adv_params.duration        = BLE_GAP_ADV_TIMEOUT_GENERAL_UNLIMITED;
    m_adv_params.interval      = 0x40;
    m_adv_params.primary_phy   = BLE_GAP_PHY_AUTO;
    m_adv_params.secondary_phy   = BLE_GAP_PHY_AUTO;
    m_adv_params.set_id         = 4;
    m_adv_params.filter_policy = BLE_GAP_ADV_FP_ANY;
}

static void advertising_init(void)
{
    ret_code_t               err_code;
    ble_advdata_t            advdata;
    ble_advdata_manuf_data_t manuf_data;

    memset(&advdata, 0, sizeof(advdata));

    manuf_data.company_identifier = COMPANY_IDENTIFIER;
    manuf_data.data.size          = ADV_ADDL_MANUF_DATA_LEN;
    manuf_data.data.p_data        = m_addl_adv_manuf_data;

    advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
    advdata.p_manuf_specific_data = &manuf_data;

    err_code = ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
    APP_ERROR_CHECK(err_code);

    err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &m_adv_params);
    APP_ERROR_CHECK(err_code);
}
