蓝牙是短距离、低成本无线通信技术之一,它可以用于替代移动设备之间的通讯电缆,从而形成个人无线网络。一个蓝牙系统在整体上可以分为底层硬件系统和上层软件系统,蓝牙软件协议是整个蓝牙结构体系中的重要核心部分,是实现蓝牙各种功能的关键因素。本文探讨了蓝牙通信的最基本也是最重要的方面,基于HCI指令的蓝牙串口通信,通过指令的探讨,利用蓝牙模块实现了PC机间的串口(RS-232)通信,并且在10m距离内达到了预期的通信效果。
Bluetooth is one of the short-range, low-cost wireless communication technologies that can be used to replace personal communication cables between mobile devices to form a personal wireless network. A Bluetooth system as a whole can be divided into the underlying hardware system and the upper software system, Bluetooth software protocol is an important core structure of the entire Bluetooth system is to achieve a variety of Bluetooth key features. This article explores the most basic and important aspects of Bluetooth communication. Based on the HCI instruction Bluetooth serial communication, through the instruction discussion, using a Bluetooth module to achieve a serial port (RS-232) communication between the PC and within 10m distance The expected communication effect.
