*Peripheral connection parameter update timeout in milliseconds*

Type: ``int``

Help
====

.. code-block:: none

    The value is a timeout used by peripheral device to wait until it
    starts the first connection parameters update procedure after a
    connection has been established.
    The connection parameters requested will be the parameters set by the
    application, or the peripheral preferred connection parameters if
    configured.
    The default value is set to 5 seconds, to comply with the Bluetooth
    Core specification: Core 4.2 Vol 3, Part C, 9.3.12.2:
    "The Peripheral device should not perform a Connection Parameter
    Update procedure within 5 seconds after establishing a connection."
