蓝牙模块使用说明书

蓝牙模块使用说明书

蓝牙模块使用说明一、模块简介:1、芯片简介该蓝牙模块采用台湾胜普科技有限公司的BMX-02X模块为核心,它采用CSR BLUEcore4-External芯片并配置8Mbit的软件存储空间,成本低,使用方便。

CSR BlueCore4是英国Cambridge Silicon Radio(CSR)公司日前推出的第四代蓝牙硅芯片。

这种硅芯片用于蓝牙技术推广小组(SIG)推出的增强数据传输率(EDR)蓝牙。

CSR的BlueCore4的数据传输率将比现有的v 1.2蓝牙装置快三倍,并且使蓝牙移动电话或手机的耗电量较低。

蓝牙EDR的最大数据传输率为每秒2.1兆比特,而目前v1.2标准传输率则为每秒721千比特。

传输率的提高意味着对一个特定量的数据来说,EDR无线电的工作将比v1.2无线电快三倍,从而减少耗电量,大大有利于依赖蓄电池的移动设备。

CSR BlueCore4完全能与现有蓝牙v1.1和v1.2装置兼容。

蓝牙EDR用一种相移键控(PSK)调制模式取代标准传输率的Gaussian频移键控(GFSK),实现更高的数据传输率。

CSR BlueCore4正在以两种形式提供——一种用于外部“快闪”存储器,一种用于掩模ROM。

BlueCore4-External以一种8×8mm BGA(球形格栅矩阵)封装提供,是十分灵活的解决方案,能够适应迅速更新的市场。

例如,由于BlueCore是目前可以得到的唯一能够支持蓝牙v1.2规格的所有强制和可选功能的硅芯片,BlueCore4-External为PC应用程序提供了理想的解决方案,使它们得益于以三倍速度的传输率无线传输文件,或者同时操作多个高需求的蓝牙链路。

鉴于蓝牙固件安装在芯片只读存储器上,CSR BlueCore4-ROM 的成本较低,占用面积小得多(在小片尺寸包装中为3.8×4mm,在与BC2-ROM和BC3-ROM引脚兼容的BGA中为6×6mm)。

购买蓝牙模块的用户,使用中请注意以下几点:
1、供电问题:蓝牙模块供电为3.3V,百米蓝牙模块供电采用两级供电,包括VCC和PAVCC,其中PAVCC 是功率扩展电源,使用中一定要两个都供给3.3V。

2、接地问题:模块中有多个GND引脚,使用中应将全部GND接地。

3、PIO引脚指示问题:在模块应用中,有的PIO是蓝牙模块工作状态指示,建议您最少引出一个做为工作状态监测引脚,如PIO5,未建链时输出800ms的脉冲信号,建链后输出200ms的脉冲信号,详细引脚功能定义请参考相应免费蓝牙固件应用说明。

4、音频应用:
音频应用中,如果您的电路板上有别的音频电路,建议将蓝牙模块单独稳压供电,减少干扰噪声。

蓝牙模块的MIC输入与SPK输出采用平衡电路接法,与外围电路连接时需要平衡非平衡转换器件,详细请看最新音频电路参考设计。

5、不用的引脚:模块中可能有许多你不需要的引脚,不用的引脚一律悬空。

6、SPI接口:SPI接口是模块固件升级和参数修改有接口,共4条线,在布设PCB板时,建议引出焊盘,便于今后固件维护。

7、GC-05/06的兼容问题:GC-05是百米蓝牙模块,GC-06是10米蓝牙模块,两者引脚完全兼容,建议您在PCB布板时,按GC-05设计,然后按需要插入GC-05、06都可以,这样在产品应用中更换10米100米不同功率的模块时,更方便。

HKL HKL--1010蓝牙模块使用说明书蓝牙模块使用说明书蓝牙模块使用说明书简介1, 采用GSR主频蓝牙芯片,V2.0协议2, 供电电压:2.7-3.3V3, 串口通信,TTL电平串口。

4, 多种通信波特率设置5, 一般工作电流:35mA,休眠电流:1mA6, 配对初始密码:04387, 支持AT指令设置设备名称、通信波特率、配对密码等。

应用电路应用电路AT AT命令集命令集命令集a 提示:如果按出厂的默认波特频率使用,不想修改波特率的下面的内容可不需理会:本AT命令用于主机和从机.成对方式使用时,主机和从机可以不同波特率也能传数据,但主机和主机相连的设备波特率要相同,从机和从机相连的设备也要同波特率.b 设置硬件连接:在发送AT命令之前确保硬件连接如下:把带底版的八PIN接口,第一脚接外接电源(3.3至5V),第六脚接电脑COM1(DB9公头)口的第三脚, 第七脚接电脑COM1口第二脚,第八脚接电脑COM1口第五脚.C 设置方式:初始通讯参数为9600,N,8,1,在配对之前(即配对指示灯闪烁时或PIO3闪动时)发送修改波特率命令使用超级终端或串口调试助手打开电脑COM1口,输入文本"AT"进行手动发送.1 测试通讯发送:AT(返回OK,一秒左右发一次)返回:OK2 改蓝牙串口通讯波特率发送:AT+BAUD1返回:OK1200发送:AT+BAUD2返回:OK2400......1 12002 24003 48004 96005 192006 384007 576008 1152009 230400A 460800B 921600C 1382400不建议用在超过115200的波特率,因为大多系统都没有115200波特率.设置超过115200后用电脑无法使用,要用单片机编程于高于115200才能使用此波特率和重新发AT命令设低波特率,否则无法恢复到低波特率了.用AT命令设好波特率后,下次上电使用不需再设,可以掉电保存波特率.3 改蓝牙名称(2008年2月24日后新增功能)发送:AT+NAMEname返回:OKname参数name:所要设置的当前名称,即蓝牙被搜索到的名称.20个字符以内.例:发送AT+NAMEbill_gates返回OKname这时蓝牙名称改为bill_gates参数可以掉电保存,只需修改一 次.PDA端刷新服务可以看到更改后的蓝牙名称.4 改蓝牙配对密码发送:AT+PIN****返回:OKset p in参数****:所要设置的配对密码,4个字节,此命令可用于从机或主机.从机则是适配器或手机弹出要求输入配对密码窗口时,则手工输入此参数就可以连接从机.主机则是在主蓝牙模块连数码相机时,数码相机是从机,找到相机的配对密码,再设入主蓝牙模块,则主蓝牙模块就可以自动连接相机.例:发送AT+PIN8888返回OKset p in这时蓝牙配对密码改为8888,模块在出厂时的默认配对密码是1234.参数可以掉电保存,只需修改一次.封装图封装图使用方法该模块为蓝牙从设备,可与各类手机、电脑等蓝牙配对使用,下面仅以计算机用蓝牙适配器为例,说明使用方法与步骤:1 安装蓝牙适配器服务程序打开“Bl u es o leil_3.2_V o IP_C h ina_070406”,安装里面的文件"set up",安装完后吧破解文件夹内的两个文件覆盖到安装目录下。
