Abstract
An apparatus, system, and method are disclosed for receiving digital instructions at devices or controllers sharing an identity. A first controller receives a digital instruction instance over a communications medium. The digital instruction instance may be a firmware instance. The first controller has ownership of the communications medium and shares the communications medium and a common identity with a second controller. An ownership module transfers ownership of the communications medium from the first controller to the second controller. The ownership module may transfer ownership in response to the first controller successfully receiving the digital instruction instance. A request module requests a retransmission of the digital instruction instance, and may request the retransmission in response to the transfer of ownership of the communications medium. The second controller receives the retransmitted digital instruction instance in response to the retransmission request.
