Revision 0.2 LMX9838DONGLE Hardware User Guide 1.0 Scope 2.0 General Description 2.1 REFERENCE DESIGN KIT CONTENTS ™ National Semiconductor LMX9838 Bluetooth serial dongle reference design kit is a plug and play serial adapter for serial cable replacement applications and more. It is able to support more profiles than just the Serial Port Profile (including audio support with external codec boards). By using the enclosed Simply Blue Commander software, it allows user to develop their own SW applications easily given the built in interpreter for HEX commands. SBSmart is a higher level application tool that provides buttons with the built in commands to easily set up or demonstrate different profile support using the Simply Blue SPP package. ■ ■ ■ ■ ■ ■ LMX9838 Bluetooth serial adapter reference board USB Dongle and application software stack Null modem cable Sedona Lite board (Audio CODEC Board) 110V to 240V AC to 5V DC power adapter and pigtail CDROM with design documents and Simply Blue software Application tools. 2.2 LMX9838 BLUETOOTH SERIAL ADAPTER REFERENCE BOARD Figure 1.
