RE: how to reduce advertising packet length?

Hello,

I guess you can check what sd_ble_gap_adv_data_set() returns, and I assume that it returns something not equal to 0 (== NRF_SUCCESS).

I suggest you refer to one of the samples that actually use advertising, such as the SDK\examples\ble_peripheral\ble_app_uart example. This doesn't have manufacturer specific data, but if you try to add:

static void advertising_init(void)
{
    uint32_t               err_code;
    ble_advertising_init_t init;

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

    init.advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance = false;
    init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
    init.advdata.p_manuf_specific_data = p_my_manufacturer_specific_data;

And this pointer needs to be a ble_advdata_manuf_data_t pointer. So initialize it something like this:

ble_advdata_manuf_data_t * p_my_manufacturer_specific_data = 
    {
        .company_identifier = 0xFFFF
        .BC_advertData;
    }

And always check the return values of the function calls where the function returns a value. If it doesn't return 0, check what that return value means.

Best regards,

Edvin
