To make the best use of high-speed serial communication capability, several methods such as modifying baud-rate of serial port driver, utilizing buffer area and adding flow-control were adopted. After analysis of scheduling and interruption handling, modifying the timer's parameters was put forward as a method to control the timer interrupt. In this way, data throughput and system stability were enhanced. Meanwhile, migration of the Bluetooth protocol stack was detailed and some successful applications of LAN access point were presented.展开更多

文摘This paper describes the design and development of a wireless LAN (WLAN) access point based on Bluetooth and uClinux. To make the best use of high-speed serial communication capability, several methods such as modifying baud-rate of serial port driver, utilizing buffer area and adding flow-control were adopted. After analysis of scheduling and interruption handling, modifying the timer's parameters was put forward as a method to control the timer interrupt. In this way, data throughput and system stability were enhanced. Meanwhile, migration of the Bluetooth protocol stack was detailed and some successful applications of LAN access point were presented.
