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.
Bluetooth is a promising new technology for short range wireless connectivity between mobile devices. Nevertheless, before the massive products come into the market, reliability of protocol stack and profiles, and interoperability of different Bluetooth products from different vendors are yet to overcome. In this article, we proposed an conformance testing architecture using emulator for different protocol stacks. Our purpose to use emulator instead of hardware is to provide a higher degree of control in testing the system for setting various parameters and test the protocol for a large number of nodes.
