The machines are configured to establish an ad hoc network between themselves for sharing information related to their common applications. New machines that come into proximity of the network infrastructure are configured to join an existing ad hoc network. Machines that power down or are removed from proximity of the network infrastructure are eliminated from the ad hoc network. Communications between the constituent machines of the ad hoc network allow the machines to self coordinate the network and redundantly store information pertaining to the common and disparate applications of the various machines that comprise the self coordinated machine network. | ||||||

| An apparatus and method for wireless/wired Bluetooth™ communications interface are described. The method includes detection of a communications configuration of a device as one of a wireless communications interface and a wireless/wired communications interface. Once detected, it is determined whether a wired/wireless communications interface is the communications interface of the device. When such is the case, a data transmission error rate of the device is determined during operation of the device in a wireless communications mode. Next, the device is switched from the wireless communications mode to a wired communications mode when the data transmission error rate caused by wireless radio interference of the device exceeds a pre-determined threshold. As such, the present invention allows Bluetooth™ wireless communications devices to utilize a wired communications mode when transmission error rate exceeds a pre-determined threshold. | ||||||
