The design and development of wireless LAN access devices based on uClinux and Bluetooth are given.In order to give full play to the hardware’s ability of high speed asynchronous serial communication, the interface baud rate in the serial port driver is modified and the buffer mechanism And add the flow control method and received good results. Starting from the analysis of the task scheduling and interrupt mechanism of the operating system, the method of modifying specific timer parameters is proposed to control the clock interruption. This method significantly improves the data throughput rate and enhances At the same time, the development of uClinux-based Bluetooth protocol stack and several key problems are discussed. And some successful applications based on Bluetooth LAN access point are given.
