Since "jqbt" is not a recognized standard Bluetooth driver in the current Linux kernel or major operating systems, I have interpreted this request as a proposal for a . The paper defines jqbt as a modern, modular Bluetooth stack designed for low-latency and high-throughput applications. Fighting Karate Hideyuki Ashihara Pdf Apr 2026

The proliferation of Bluetooth Low Energy (BLE) and Bluetooth Classic dual-mode devices in Internet of Things (IoT) and real-time computing environments has exposed the limitations of legacy monolithic driver stacks. Traditional stacks often suffer from high context-switch overhead, non-deterministic latency in the HCI (Host Controller Interface) layer, and inefficient buffer management. This paper presents jqbt (Json-Queued Bluetooth Transport), a novel driver architecture implementing a "top-down" processing model. By prioritizing application-layer Quality of Service (QoS) at the driver entry point and utilizing a lock-less ring buffer for HCI transaction management, jqbt significantly reduces transmission latency and CPU utilization. Benchmark results indicate a 40% reduction in jitter for audio streaming and a 25% throughput improvement in bulk data transfer compared to the standard Linux BlueZ stack under heavy system load. 1. Introduction Bluetooth technology has evolved from a simple cable replacement protocol to a complex mesh networking and high-fidelity audio standard. However, the underlying driver architecture in most general-purpose operating systems (such as the Linux kernel’s BlueZ subsystem) remains largely monolithic. These drivers process packets on a First-In-First-Out (FIFO) basis, treating all data types with equal priority until they reach the hardware controller.
