Is it possible to reject a connection parameters update request?

[Boaz]

In sample code for central devices,, the BLE event handler, on_ble_evt(), handles the `BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST' by accepting the request.

Is it possible to reject the request?

nRF5 SDK 11.0.0, with PCA10040 EVB

Respond with sd_ble_gap_conn_param_update() and pass NULL for p_conn_params.

     * @param[in] conn_handle Connection handle.
     * @param[in] p_conn_params  Pointer to desired connection parameters. If NULL is provided on a peripheral role,
     *                           the parameters in the PPCP characteristic of the GAP service will be used instead.
     *                           If NULL is provided on a central role and in response to a @ref BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST, the peripheral request will be rejected

sd_ble_gap_conn_param_update(uint16_t conn_handle, const *p_conn_params);
