BtFree is a library for creating client-server applications that communicate over a Bluetooth connection. You can use it in your MIDP application or in a Java application that uses an implementation of JSR82. It allows you to create applications with client-server interaction easily, avoiding the need to know JSR82 and the problems related.
JRemote Control is a simple Bluetooth remote control. It allows you to initiate virtually any task on your PC from J2ME and Bluetooth enabled mobile devices. An easy-to-use program interface is provided to allow you to create your own configuration to map tasks on your PC to remote device commands. Additionally, any output task can be shown directly on your mobile device display. The default configuration supports mplayer on the Windows and Linux platforms. Additional packages are available.
