Can I put measured data in the Scan Response packet?

[Sensors]

I'm looking at an application where it would be beneficial to be able to read data from the bluetooth device as it passes. It would be easiest for me to do this by simply reading the scan response data if it was possible to put the measured data in there somehow.

Is this possible? It seems in the examples the scan response packet is set when he advertising is initialised, so can I change it afterwards?

My existing advertising initialisation is this:

static void advertising_init(void)
{
    uint32_t      err_code;
    ble_advdata_t advdata;

    // Build advertising data struct to pass into ble_advertising_init().
    memset(&advdata, 0, sizeof(advdata));

    advdata.name_type               = BLE_ADVDATA_FULL_NAME;
    advdata.flags                   = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

    ble_adv_modes_config_t options = {0};
    options.ble_adv_fast_enabled  = BLE_ADV_FAST_ENABLED;
    options.ble_adv_fast_interval = APP_ADV_INTERVAL;
    options.ble_adv_fast_timeout  = APP_ADV_TIMEOUT_IN_SECONDS;
    
    // Create a scan response packet and include the list of UUIDs 
	ble_uuid_t m_adv_uuids[] = {BLE_UUID_OUR_SERVICE, BLE_UUID_TYPE_VENDOR_BEGIN};
	
	ble_advdata_t sr_data;
	memset(&sr_data, 0, sizeof(sr_data));
	
	sr_data.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
	sr_data.uuids_complete.p_uuids = m_adv_uuids;

	err_code = ble_advertising_init(&advdata, &sr_data, &options, on_adv_evt, NULL);
    APP_ERROR_CHECK(err_code);
}

Change it whenever you want, change the advertising data or the scan data or both of them. Just set it and the next advertisement will go out with the new data.

I use manufacturer data to transmit basic state on my device, including when it's in connection (just make the advertising non-connectable). It's easy.

So I'd just update the ble_advdata_t sr_data; whenever I wanted it to change? How would I make advertising non-connectable?
