OVERVIEW
The Bluetooth HID profile is typically used in applications such as keyboards, mice, and game controllers. To demonstrate
the basic capability of the Bluetooth HID profile, Roving Networks has developed a Bluetooth reference design
implemented in the RN-42 module. This document describes the reference design and how to use it.
The reference design operates in three modes:
• Presenter mode—Used for presentation software such as Microsoft® Powerpoint
• Music mode—Music controller for products such as the iPod, iPhone, and iPad
• Custom mode—You can program each button to send a sequence of up to 4 keys
Figure 1 shows the iRemote controller and Table 1 describes the button operation for a short button press.
