Abstract
A method to establish peer to peer communication in a system utilizing a master-slave protocol which allows a first slave device (504) to act as the master and communicate with a second slave device (506) such as an accessory to the first slave device. The first slave device sends a message comprising a data set and a functional address (608), which represents a function in the second slave device to a host device, which now acts as a router, which then forwards the message on to the second slave device. This allows the slave devices to communicate with one another without direct control by the host or master device.
