The Victorinox Bluetooth Controller is a specialized electronic radio frequency wireless controller tool that currently only appears on versions of the 58mm sized Presentation Master.
The Bluetooth Wireless Controller is embedded in the bottom scale of some Swiss Army Knives, and features two control buttons. With compatible software and a Bluetooth receiver, the Swiss Army Knife becomes a wireless remote-control for the computer software.
The wireless-controller and its associated software are designed to control the advancement of the slides during a presentation, freeing the speaker from having to be in the immediate vicinity of the controlling computer's keyboard or mouse. Pressing the up or down button on the scale acts, respectively, as a left or right mouse button press.
The Broadcom BCM2042 chip used in the scale is a major breakthrough in the design of low-cost Bluetooth mouse and keyboard devices. The BCM2042 is a true single chip that integrates the entire profile, application, and Bluetooth protocol stack and is fully compliant with the Bluetooth SIG specification for human interface devices. The BCM2042 is fully compliant with the version 2.0 Bluetooth specification, including adaptive frequency hopping and fast connection, which are essential to mouse and keyboard applications in personal computers.
