Bluetooth Group Network Profile (GNP) plays a key role in Bluetooth to support an ad-hoc networking and provides the solution of communicating among the Bluetooth devices in a single Piconet. There are several challenges in implementing GNP. The paper provides the related solutions of dynamic IP address assignment, transmission of the broadcast and multicast packets, and profile security architecture. Furthermore, the implementation reduces the code size and increases the portability in the embedded environment.
