android 蓝牙连接通信工作原理
Android 蓝牙连接通信的工作原理可以分为几个主要步骤:1. 开启蓝牙模块:Android设备上的蓝牙功能由BluetoothAdapter类管理。
首先,需要获取BluetoothAdapter的实例,并调用其enable()方法来开启蓝牙模块。
2. 搜索蓝牙设备:开启蓝牙模块后,可以调用BluetoothAdapter的startDiscovery()方法开始搜索附近的蓝牙设备。
搜索过程中,设备会广播其信息,包括蓝牙设备的名称、地址、服务等信息。
3. 建立连接:当搜索到目标设备后,需要创建一个BluetoothDevice对象。
使用该对象调用connectGatt()方法来尝试与蓝牙设备建立连接。
此方法返回一个BluetoothGatt对象,用于后续的GATT通信。
4. GATT通信:GATT(Generic Access Profile)是蓝牙4.0及以上版本中定义的一套协议,用于在蓝牙设备之间传输数据。
通过BluetoothGatt对象,可以进行一系列GATT操作,如读取服务、读取特征值、写入特征值等。
GATT操作通常是异步的,需要通过回调函数来处理结果和状态变化。
5. 数据交换:一旦GATT连接建立,就可以通过BluetoothGatt的readCharacteristic()和writeCharacteristic()方法来读写数据了。
数据交换可以是特征值之间的直接读写,也可以是通过服务端点进行。
6. 断开连接:当通信完成后,应该断开与蓝牙设备的连接以节省能源。
可以调用disconnect()方法来断开连接。
断开连接后,应该释放相关的资源。
在整个过程中,蓝牙通信涉及到多种蓝牙技术,包括经典的蓝牙(Bluetooth Classic)、蓝牙低能耗(Bluetooth LE,也称为BLE)、蓝牙高级(Bluetooth High Speed)等。
不同的技术有不同的通信范围和速度要求。
另外,为了确保通信的安全性,蓝牙通信过程中可能还需要进行配对和认证操作。

The ARF52 module fully complies with the V2.0+EDR Bluetooth® standard and data rate goes up to 3 Mbps. Data exchange and set-up are only done through an UART data port, under SPP profile. A miniature antenna is integrated. A RF52 can be used in two modes : command mode and transparent mode. The command mode is used to established Bluetooth communications and set/get parameters. The transparent mode is used for data exchange. The module converts data from a serial link into a Bluetooth ® radio frame to be sent to a similar piece of equipment. The communication is half-duplex. The operating parameters of the Bluetooth module (serial link, Bluetooth® management…) can be fully updated through AT commands via the serial link. A RF52 m od ules are available as standalone ARF7456 module or in a DemoKit. This DemoKit can be fully set-up using a PC terminal. We recommend reading the “specification of the Bluetooth® system core 2.0 + EDR” document available at the web site.InterfaceMechanical specification (cf next page)A RF52User GuideRef. 08-12-V5-pcy5 pA RF52 User GuideRef. 08-12-V5-pcySignal description14 pins 1,27mm male SMD connector.Interface PinName I/O Description Digital interface1,10,11 GND Ground13 VDD_DIG Digital voltage 3,3V +/- 10%14 VDD_ANA Analog voltage 3,3V +/- 10%4 TXD O Serial data transmission6 RXDI Serial data reception2 /CTS I Clear To Send CTS = GND, the DCE is able to receive serial data CTS = VDD, serial data received by the DCE are lost3 /RTS O Request To Send RTS = GND , the DTE is able to receive serial data RTS = VDD , serial data received by the DTE are lost12 /RESET I Reset signal9 (PIO7) DTR I/O Data Terminal ready Output for the Slave Input for the Master5 (PIO6) DSR I/O Data Set Ready Input for the Slave Output for the Master7 (PIO5) RI I/O Ring Input for the Slave Output for the Master8 (PIO4) DCD I/O Data Carrier Detect Input for the Slave Output for the MasterA RF52 User GuideRef. 08-12-V5-pcyProfilesThe module supports 2 different profiles: SPP and DUN .A basic module configuration is provided as a guideline for each profile (for more details or customisation see § AT commands).The module can be configured using a terminal at 9600 baud, 8 bits, 1 stop, HW flow control (default serial configuration)SPP wiring and configurationSPP (Serial Port Profile) is the standard Bluetooth® profile.SPP configuration guideline : in the following example, the Master is configured to performed an auto-connection on reset.1. Master configuration : enters the command mode using the A+++ sequence. When the <OK> answer is receive, send the following commands:2. ATS202=1 (auto-connect on reset)ATS220=1 (SPP profil, default value)ATS203= slave BT address (use ATINQ 0,10 command to discoverthe slave @) AT&W (save the configuration)3.Slave configuration : enters the command mode and then send the following commands:ATS202=0 (auto-connect disable, default value)ATS220=1 (SPP profil)AT&W (save the configuration)4.Perform a power cycle on both modules. The modules are now in transparent mode; the link will be established automatically on reset by the master.When the link is established data can be exchanged using the serial link.5.Caution the BT connection establishment can take up to 10 seconds (you can check this establishment in command mode using the AT&L command).DUN wiring and configurationDUN (Dial up Network) profile is above the SPP profile. This profile manages the 4 lines DTR, DSR, DCD and RI and is dedicated to PSTN or GSM modems.DUN configuration guideline : in the following example, the Master is configured to performed an auto-connection on DSR.Ref. 08-12-V5-pcy1.Master configuration : enters the command mode using the A+++ sequence. When the <OK> answer is receive, send the following commands: ATS202=2 (auto-connect on DTR)ATS220=2 (Dun profil)ATS203= slave BT address (use ATINQ 0,10 command to discoverthe slave @)AT&W (save the configuration)2.Slave configuration : enters the command mode and then send the following commands :ATS202=0 (auto-connect disable, default value)ATS220=2 (Dun profil) AT&W (save the configuration) 3.Exit the command mode or perform a power cycle on both modules. The modules are now in transparent mode; the link will be established when the DTR is activated on the master. When the link is established data can be exchanged using the serial link. 4.Caution the BT connection establishment can take up to 10 seconds (you can check this establishment either in command mode usingthe AT&L command or by checking report of a remote signal).DTR/DSR/RI and DCD I/O configuration :¾These lines are set as inputs while the connection is not established or released,¾And set as input and output according to the DUN illustration andto the description done in signal description table.Module operating modeTwo operating modes are available :- Command mode (usage of AT commands and SPP_CONFIG mode)- Transparent mode (serial data are transmitted on radio link).At power up the transceiver is in transparent mode according to the registers configuration. The boot time is about 1s.Ref. 08-12-V5-pcyCommand modeThe command mode is used to read and update the modem configuration registers using AT commands.In command mode, the radio is inhibited (reception and transmission), excepted when using test command.Entering command mode : issues on the serial link a A+++ sequence. The sequence A+++ characters is accepted only if no character has been seen before and after the A+++ sequence. Register (S214) defines the silence duration.Tips : if you are using a terminal (such as Hyperterm), you have to send the A+++ sequence using a text file (first create a text file containing only the A+++ characters, and then use in Hyperterm the command “Send text file” in the “Transfer menu”)Exiting command mode (return back in transceiver mode) : send the serial commandATO <cr>Transparent modeIn transparent mode, data received from the serial link are transmitted on the radio link. When data are received on the radio link, these data are sent on the serial link.Ref. 08-12-V5-pcyRemote control configurationSPP_CONFIG mode is used to remotely configure the slave module through the master module serial link. This is done, on master side, in 4 steps : Activation of the SPP_CONFIG mode using the ATC1 command. When this mode is activated, the command issued on the master will be ignored by themaster and transmitted to the slave by radio.Slave configuration : send command to the slave using the Master serial link. When the remote configuration is done, the master must sent an AT&W command to the slave (the AT&W command is mandatory because the slave reboots when the master leaves the SPP_CONFIG mode or when the RF link is loosed).Leaving of the SPP_CONFIG mode using the ATC0 command.AT CommandsDescriptionAT commands are interpreted only when the module is in Command mode.Commands : are used to read and update the modem parametersA command starts with the 2 ASCII ‘AT’ characters. ‘AT’ means ‘Attention’ follow with one or several characters or other data.Each command is ended with <cr> (carriage return).In the same command, the time between 2 characters must be less than 10s. Response : is sent back for each command on the serial link. The answer is: <cr><lf ‘OK’<cr><lf> (ASCII character 0x4F) for accepted command (or OK command)<cr><lf ‘ERROR’<cr><lf> for error•Specific string when specifiedRef. 08-12-V5-pcySet of commandsThe SPP CONFIG column indicates whether the command is available or not when the module is in SPP CONFIG mode (ATC1 command).Commands Description SPPCONFIGOperating mode selectionATO Return back to transparent mode.

基于Android4.0的蓝牙防丢失报警功能实现
DOI:10.19392/j.cnki.1671-7341.201912065基于Android4.0的蓝牙防丢失报警功能实现李雨航蒋玮杰刘元刘毅文怀化学院湖南怀化418000摘要:文章首先分析了以Android4.0为基础的蓝牙防丢失警报系统的运行原理,随后介绍了以Android4.0为基础的蓝牙防丢失警报功能的实现,包括设计思想、结构设计、定位代码设计等,希望能给相关人士提供一些参考。
关键词:Android4.0;蓝牙防丢失;报警功能一、以Android4.0为基础的蓝牙防丢失警报系统的运行原理Android4.0系统也被称作是冰淇淋三明治,简称ICS,是谷歌推出的一种操作系统,其拥有十大特征,运行速度有所提高。
Android4.0中还拥有新型设计的人性化UI界面,UI设计也将更加成熟。
随着众多生产厂商开始研制双核智能手机,Android4.0也将对双核或是多核处理器进行优化设计,将手机中的双核性能全面发挥出来。
以Android4.0为基础的蓝牙防丢失警报系统主要包括设备元件与手机等两部分内容,其中手机主要发挥的功能是寻找信号和接收信号等,设备主要功能就是报警系统与信息接收,尽管一部手机可以同时配对多种设备,但是在相同的时间里只能和一项设备进行连接,手机和设备之间的距离也不可以大于设备接收限制,不然两者之间的联系就是立刻中断,具体运行流程如下,首先是将手机中的APP软件打开,和相应的设备进行连接,在功率抵达范围之内,在这种条件下手机中的APP软件就不会自动报警或是弹出各种消息。
其次手机与设备之间处于一种断开或是没有连接的状态。
手机中的APP软件就会自动给予提示,需要将振动与定位打开,将设备所处位置准确显示出来,设备能够自动闪光,出现蜂鸣和振动。
再次,设备应该附带与随身装置的物品当中,因此应该对设备进行科学设计,从而保证设备的随身携带性,比如可以将设备设计成一种书签的形式或是锁扣的形式,只能应用小型的电池,保证设备的附着力。

标题:探索正点原子蓝牙开发:一步一步教你编写蓝牙代码程序引言:正点原子是一家致力于电子原型设计的公司,他们的产品遍及各个领域,为开发者和爱好者提供了许多创新的工具和设备。
其中,正点原子蓝牙模块是一个非常重要的部分,通过它,我们可以实现与其他设备的无线通信。
本文将从头开始,一步一步教你如何编写一个正点原子蓝牙代码程序。
第一步:理解正点原子蓝牙模块在开始编写蓝牙代码程序之前,我们首先需要理解正点原子蓝牙模块的基本工作原理和功能。
正点原子蓝牙模块是一种无线通信设备,基于蓝牙协议,能够与其他蓝牙设备进行通信。
它通常由一个主控芯片、一个蓝牙模块和相关的电路组成。
我们需要了解模块的通信方式、接口和功能,以便在编写代码时能够正确地使用和操作。
第二步:准备开发环境要编写正点原子蓝牙代码程序,我们需要一个合适的开发环境。
正点原子公司提供了一套完整的开发工具和文档,包括开发板、编译器、调试器和相关的软件库。
我们需要准备好这些工具,并且学习如何使用它们。
第三步:学习蓝牙协议和API蓝牙通信是基于一种特定的协议进行的,我们需要学习并理解这个协议的工作原理和规范。
正点原子提供了一套蓝牙开发文档,其中包括了蓝牙协议和API的详细介绍。
我们需要仔细研读这些文档,了解蓝牙通信的各个方面,包括设备发现、连接、数据传输等。
第四步:编写代码程序在掌握了蓝牙协议和API的基础上,我们可以开始编写代码程序了。
首先,我们需要创建一个新的项目,包括主函数和相关的初始化代码。
然后,我们可以使用蓝牙API来实现设备的发现和连接。
在连接建立后,我们可以使用API来进行数据的传输和交互。
在编写代码时,我们需要注意以下几点:1. 确保正确的函数调用和参数传递,遵循API的规范和要求。
2. 处理错误和异常情况,包括设备不可用、连接断开等。
3. 优化代码和算法,提高蓝牙通信的效率和稳定性。
4. 做好代码注释和文档,方便其他开发人员理解和维护。
android10 writecharacteristic false -回复
android10 writecharacteristic false -回复标题:探究Android 10中的writeCharacteristic功能导言:随着移动设备发展的迅猛,人们对于手机等智能终端设备的需求越来越多样化。
为了能够满足用户的个性化需求,操作系统也在不断的进行升级与改进。
作为当前最先进的智能手机操作系统之一,Android 10引入了许多新功能来满足用户的期待。
而其中写特性(writeCharacteristic)功能为开发人员提供了更多的控制权限,本文将对该功能进行深入探究。
一、什么是writeCharacteristic?writeCharacteristic是指在Android 10操作系统中,应用程序可以使用该功能向蓝牙设备的特性(characteristic)写入数据。
在此之前,仅仅只能读取设备特性的数据,而writeCharateristic的引入使得开发人员能够更加灵活地处理与蓝牙设备之间的数据交互。
二、为什么需要writeCharacteristic?在很多应用中,只通过读取蓝牙设备的特性可能无法满足用户的需求。
例如,想象一下你正在使用一台蓝牙音箱,你想要调整音量。
若只能读取特性数据,你将不能向音箱发送指令来实现音量调节。
而writeCharacteristic的引入为开发人员提供了这样的可能性。
三、如何使用writeCharacteristic?要使用writeCharacteristic,开发人员需要使用BluetoothGatt类。
以下是一步一步的使用指南:1. 连接蓝牙设备首先,需要使用BluetoothAdapter获取蓝牙设备的Gatt连接。
连接成功后,得到一个BluetoothGatt对象。
2. 获取服务和特性在成功连接蓝牙设备后,我们需要获取设备的服务(service)和特性(characteristic)。
使用BluetoothGatt对象的getServices方法来获取服务列表。

BT321蓝牙发射模块设置TF或者U盘或者spiflash单曲触发明
一、简介BT321F支持发射的音源有U盘、TF卡、spiflash。
一旦搜索到相应的从机之后,会自动发射当前在线设备的音源,U 盘》TF卡》spiflash。
播放的方式,是采取单设备不间断的循环播放下去,直到用户干预二、问题2.1指定播放的模式指令[AC指令]AT+AC00设置为全部循环AT+AC01设置为单设备循环AT+AC02设置为单曲循环AT+AC03设置为单设备随机播放AT+AC04设置为文件夹循环1、如果只需要单曲循环和全部循环,则只用选择自己需要的即可。
多余的可以不管2、全部循环指的是两个设备循环,前提条件是你有两个设备在线,如果只有一个设备,就还是一个设备循环3、单设备,就是指一个设备。
只在这个设备内循环4、文件夹循环,如果当前播放的曲目是在文件夹内的,那么他会循环播放这个文件夹,否则无效注意此指令只能改变播放的模式,播放完毕之后还是会继续播放,毕竟这个才是最常用的功能。
2.2单曲触发模式-即播放完毕就停止的指令说明【CJ】AT+CJ01\r\n开启--单曲触发播放AT+CJ00\r\n关闭--循环顺序播放1、对于MUSIC的播放,我们这里给出了两种的应用方式(1)、基础的方式,进入到music就是循环顺序播放,播放接着播,不停止。
这叫做“循环顺序播放”(2)、个性化方式,进入到music就是停止,等待用户指定播放,并且播放完成则停止。
这叫做“单曲触发播放”2、这个的设置是带记忆的,设置完了之后,当时就生效,掉电自动保存此条指令,最好在开机的时候就设置一下。
这样连接到从机设备之后,芯片自动待机1。

bluetoothgattservercallback 回调方法描述 -回复
bluetoothgattservercallback 回调方法描述-回复BluetoothGattServerCallback 是一个用于管理和处理GATT 服务器(Generic Attribute Profile server)相关事件的回调接口。
GATT 服务器是用于与GATT 客户端进行通信的BLE(蓝牙低功耗)设备的一部分。
本文将详细介绍BluetoothGattServerCallback 回调方法的使用和相关应用。
首先,我们需要了解GATT(Generic Attribute Profile)的概念。
GATT 是BLE 设备用于通信和交换数据的协议规范。
GATT 服务器和客户端之间通过GATT 特征(characteristic)和服务(service)进行交互。
服务用于组织多个相关特征,而特征则包含数据和行为。
GATT 服务器有时也被称为外围设备(peripheral)。
BluetoothGattServerCallback 是GATT 服务器用于处理来自GATT 客户端的请求和事件的回调接口。
接下来,我们将详细介绍该回调接口的各个方法及其功能。
1. onCharacteristicReadRequest: 当GATT 客户端请求读取某个特征的值时,系统将调用此方法。
在该方法中,我们可以通过特征的UUID 和请求的设备(device)进行一些处理,例如向客户端返回特征的值。
这个方法对于外围设备提供访问服务和特征值的机会。
2. onCharacteristicWriteRequest: 当GATT 客户端请求写入某个特征的值时,系统将调用此方法。
在该方法中,我们可以通过特征的UUID、请求的设备和待写入的数据进行一些处理,例如将数据写入外围设备的特征中。
这个方法对于外围设备接收来自客户端的数据非常重要。
3. onConnectionStateChange: 当与GATT 客户端的连接状态改变时,系统将调用此方法。

目前已被广泛的用于各类电子产品,汽车、消费娱乐、影像、工业控制、海量存储、网络、安保和无线等领域。
被业界人士认为,基于ARM的技术方案是最具市场前景和市场优势的解决方案。
LPC2131Philips LPC2131 是基于ARM7TDMI-S 的高性能32 位RISC 微控制器,它一方面具有ARM处理器的所有优点:低功耗、高性能;同时又具有较为丰富的片上资源,非常适合嵌入式产品的开发。
其特点如下:·集成了Thumb 扩展指令集。
·32KB可在系统中编程(ISP)的片内Flash和可在应用中编程(IAP)的8KB RAM,具有向量中断控制器。
·2个UART,2个I 串行接口,2 个SPI串行接口,2 个定时器(7 个捕获/ 比较通道),PWM 单元可提供多达6个PWM输出,8通道10位ADC,实时时钟RTC,看门狗定时器WDT,48 个通用I/O引脚。
·CPU时钟高达60MHz,具有片内晶体振荡器和片内PLL。
GPIO:(General Purpose Input Output)GPIO是用来进行输入输出的,那么肯定有寄存器进行控制。
对于输入的话,可以通过读取寄存器来确定引脚的高电平还是低电平;对于输出的话,可以通过写某个寄存器来让这个引脚输出高低电平.GPxCON,GPACON每一位对应着一根引脚(23根)0:代表输出;1:相应的引脚为地址线或用于地址控制对于PORT B-PORT J的话,GPxCON中每两位控制一根引脚00:输入;01:输出;10:特殊功能;11:保留。
