1.5 Bluetooth Support
The functionality of your Preface implementation will depend on whether the PM you
choose supports Bluetooth, in addition to USB. Bluetooth support changes how SideShow
protocol is supported, and adds functions that are not supported with USB alone. Table 2
shows how Bluetooth support affects Preface functionality.
