Patent ID: 7856520

Claim:
A method comprising: coupling a first device to a second device, the first device being one of a transmitting device or a receiving device and the second device being the other of a transmitting device or a receiving device, coupling of the first and second devices including connecting a first control bus between the first device and the second device, the first control bus being a bi-directional, single-line bus; determining whether the first control bus is in use by the second device; if the first control bus is not in use by the second device, conducting arbitration for control of the first control bus; and if the first device obtains control of the first control bus through the arbitration for control of the first control bus, the first device becoming an initiator and the second device becoming a follower, then further comprising: converting one or more control signals for a standard protocol to one or more data packets, each of the one or more control signals representing one of a plurality of different types of control signals, each data packet including a plurality of bits to be transmitted; and transmitting the generated data packets from the first device to the second device via the first control bus, and wherein the receiving device is a device utilizing the standard protocol and the transmitting device is a mobile device utilizing a modified protocol, the modified protocol being a modification of the standard protocol that is not included in the standard protocol.
