Scope
National Semiconductor LMX9838 Bluetooth
evaluation kit is a plug and play serial adapter for serial
cable replacement applications and more. It is able to sup-
port 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 com-
mands to easily set up or demonstrate different profile sup-
port using the Simply Blue SPP package.
