INTRODUCTION
Developing wireless applications can be challenging.
Apart from Radio Frequency (RF) circuit designs, the
firmware development process may require the devel-
opers to understand the details of RF transceivers, as
well as the different wireless communication protocols.
Microchip has developed a way to handle the complex
RF hardware or communication protocol stack software
development, or both, which enables wireless applica-
tion developers to focus on their own application devel-
opment. This type of wireless communication is
achieved through a concise, yet powerful communica-
tion programming interface in the application layer
called MiApp which is defined in this application note.
The MiApp specification defines the programming
interfaces between the application layer and Microchip
proprietary wireless communication protocols. The
MiApp programming interface is implemented in two
ways: as configuration parameters defined in the con-
figuration file, and as a set of function calls to the Micro-
chip proprietary wireless communication protocols.
Complying with the MiApp specification defined in this
application note, applications can use any Microchip
proprietary wireless protocols. With little or no modifica-
tion in the application layer, software development can
be easily changed between a proprietary P2P/Star
topology connection protocol to a full Mesh proprietary
networking protocol for small or big networks, depend-
ing on the application needs.
