Running the below function on our side did not give any errors , Make sure the rest of the uninitialized parameters does not contain random value.

static void advertising_data_set(void)
{
    ret_code_t ret;

    ble_gap_adv_params_t const adv_params =
    {
        .properties    =
        {
          .type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED,
        },
        .p_peer_addr   = NULL,
        .filter_policy = BLE_GAP_ADV_FP_ANY,
        .interval      = ADV_INTERVAL,
        .duration      = 0,

        .primary_phy   = BLE_GAP_PHY_1MBPS, // Must be changed to connect in long range. (BLE_GAP_PHY_CODED)
        .secondary_phy = BLE_GAP_PHY_1MBPS,
    };

    ble_advdata_t const adv_data =
    {
        .name_type          = BLE_ADVDATA_FULL_NAME,
        .flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE,
        .include_appearance = false,
    };

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

    ret = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);
    APP_ERROR_CHECK(ret);
}

Hi Aryan

I did as you suggested

adv_params.primary_phy = BLE_GAP_PHY_CODED; // BLE_GAP_PHY_1MBPS;
adv_params.duration = APP_ADV_DURATION;
adv_params.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_CONNECTABLE_NONSCANNABLE_UNDIRECTED; //BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED;
adv_params.p_peer_addr = NULL;
adv_params.filter_policy = BLE_GAP_ADV_FP_ANY;
adv_params.interval = APP_ADV_INTERVAL;

err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);
NRF_LOG_INFO("err_code = %d", err_code);
APP_ERROR_CHECK(err_code);
}

to look at the error code

<info> app: err_code = 7
<error> app: Fatal error

and looking up error code 7 I find

#define NRF_ERROR_INVALID_PARAM (NRF_ERROR_BASE_NUM + 7) ///< Invalid Parameter

Please start the application in the debugger and step through to code by putting a breakpoint in app_error_handler function.

You system is restarting due to some APP_ERROR_CHECK. failure. You should find which check failed by debugging as mentioned above and fix the function parameters that caused it to return error. When a function returns error then the line APP_ERROR_CHECK(err_code) will reset your device when not in debug mode.
