At its heart, the BM Driver (often referred to in forums as "Button Box & Joystick over IP") operates on a client-server model. The architecture consists of two primary components. On the host machine—the computer physically connected to the USB joystick—a server application runs. This server captures raw HID (Human Interface Device) reports from the joystick, including axis positions (X, Y, Z, throttle, rudder) and digital button states. It then packages this data into small UDP or TCP packets and streams them across a local area network (LAN) or, theoretically, the internet.
