Mobile phone has become a part of our life and plays very important role. With the development of technology, means of communication has become increasingly diverse. The understanding of people for the cell phone is no longer limited in the traditional function of “any call”. The hardware capability of mobile phone has been improved and the corresponding value-added services are increasingly diversified. J2ME has become the ideal development tool because of its outstanding characteristic of easy development and cross-platform deployment.
Bluetooth technology is a low-cost, short-distance wireless communication technology. Bluetooth technology is not a new technology, but using J2ME to develop Bluetooth application on MIDP platform is a new technology. The new technology has been supported by many mobile devices manufacturers and services operators.
Therefore, my research topic is “Based on J2ME Bluetooth phone chat software”. It uses NetBeans as its IDE. Users can chat through Bluetooth network and use RMS (Record Management System) to store the chatting information, which makes it easy to review the chatting anytime and understand the chatting processes. This system is based on search / discovery technology of Bluetooth and integrates client / server which makes two Bluetooth mobile phones easily connect to each other. It can well coordinate the function of receiving and sending information via the thread mechanism.
