sd_ble_gap_adv_set_configure() returns NRF_ERROR_INVALID_PARAM

Hello,

I am recompiling a system from a nRF52832 to the nRF52840.

This is a BLE peripheral. I started with a working ble peripheral example so that I was able to start with the new sdk_config.h and project solutions (Segger) so I believe these are correct as I am able to compile and execute the code.

When the code runs I get an error code 7 (NRF_ERROR_INVALID_PARAM) returned from sd_ble_gap_adv_set_configure().

Here is my advertising_init():

/**@brief Function for initializing the Advertising functionality.
 */
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.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.srdata.uuids_complete.p_uuids  = m_adv_uuids;

    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_DURATION;
    init.evt_handler = on_adv_evt;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);

    ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
    SEGGER_RTT_printf(0,"ADV INIT: Num SYSTEM UUIDS:%x\n",init.srdata.uuids_complete.uuid_cnt);
}

My error occurs here:

At the point of error above, p_advertising is as follows:

Any help would be greatly appreciated!
