From some years ago, technologies are ubiquitous, omnipresent and integrated seamlessly in our common activities. There is a need for developing services and applications that use all the capabilities of mobile devices available, for connectivity and data processing. Java 2 Micro Edition (J2ME) technology develops these services for use in a wide range of devices, with portable code, and compatible with several classes of hardware and software. Wireless communications technologies (WiFi, Bluetooth) allow devices to communicate with their environment. Bluetooth technologies are becoming massive, and are present in the majority of these devices. This kind of connectivity is possible using the J2ME Application Programming Interfaces (APIs), but it requires some expertise and a wide knowledge in order to implement these components. This document proposes a framework focused towards the service development using bluetooth technologies with more simplicity. Also, it presents the design and implementation of a mobile information service that uses this framework in a ubiquitous environment.
