学习蓝牙core_v5.3核心重要文档，是目前中英文对照版本最好的

基于STM32与TB6600蓝牙控制机械臂项目，机械臂运动驱动由3台42步进电机驱动，机械爪部分则是5V步进电机与ULN2003步进电机驱动工作。代码采用CubeMX配置初始化，Keil平台进行编写。除了提供作者的STM32版本的控制代码与硬件设计，也提供开源版本的Arduino版本代码。整体代码与机械结构方便后续二次开发，积分不够的朋友可以点波关注私聊博主，博主无偿提供！！！

Bluetooth是几乎现在每部手机标准配备的功能，多用于耳机mic等设备与手机的连接，除此之外，还可以多部手机之间建立bluetooth通信，本文就通过SDK中带的一个聊天室的例程，来介绍一下Android上的Bluetooth的开发。

简单蓝牙聊天室的功能，直接可以导入运行 主要蓝牙聊天室的案列框架分析，分UI界面分析以及蓝牙后台服务设计 采用Android studio开发

目前市场中基于CC254x的蓝牙BLE居多，但大家注意，BLE只支持IOS和安卓4.3以上的手机。但目前安卓手机中大部分还是安卓4.3以下版本，所以这就是双模蓝牙存在的原因。请开发者一定注意。蓝牙模块HM-13具有双模式，包括EDR和BLE。HM-13蓝牙模块采用CSR双模蓝牙芯片，配合新唐ARM构架单片机，支持AT指令，用户可根据需要修改串口波特率、设备名称、配对密码等参数，使用灵活。 串口配置: 115200, N, 8, 1, EDR: HMSoft: 从模式, 不休眠, 透传模式, 配对密码 1234 BLE: HMSoft: 从模式, 不休眠，透传模式, 不需要配对密码 SPP传输速度较快，BLE传输速度较慢，因此我们在设计产品的时候选取的是下限，即依照BLE的速度来规划双模产品。在保证稳定的前提下，我们也会在随后发布的新版本中逐步提高传输速度。 ----主从一体，透明传输，替代串口线----远程控制，透明传输，无须单片机 ----远程数据采集、透明传输，无须单片机 CSR蓝牙4.0双模HM-13蓝牙模块实物截图: CSR蓝牙4.0双模HM-13蓝牙模块特点: BT版本:蓝牙规范V4.0＆BLE UART发送和接收最大字节为512 SPP模式下的其他设备模块:每个数据包为90字节 BLE模式下的其他设备模块:每个数据包为20个字节 两种数据传输模式，平衡模式和高速模式 工作频率:2.4GHz ISM频段 调制方式:GFSK（高斯频移键控） 射频功率:-23dbm，-6dbm，0dbm，6dbm。 速度:异步:3K字节 同步:3K字节 安全性:认证和加密 服务:从SPP，外设BLE，UUID FFE0，FFE1 电源:+ 3.3VDC 50mA 长距离:SPP 30米，BLE 60米 电源:SPP 13.5mA，BLE 9.5mA 工作温度:-5〜+65摄氏度

《蓝牙协议及其源代码分析》——金瓯科技电子版 重点阐述和分析了蓝牙规范V2.0的协议体系结构和相关内容，包括射频协议（RF）、基带协议（BB）、链路管理器（LMP）、主机控制接口（HCI）、逻辑链路控制与适配协议（L2CAP）、串口仿真协议（RFCOMM）、对象交换协议（OBEX）、服务发现协议（SDP）、电话控制协议（TCS）和蓝牙操作模式，并对L2CAP、RFCOMM和SDP等三层协议中的数据和源代码进行了验证和分析。

BLE 智能锁功能概述: 众所周知，平时生活中的锁都是有锁槽，需要钥匙开启的，而BLE 智能锁，可以把用户从钥匙中解放出来，只需智能手机上的应用就能控制琐的开启，可用于自行车、摩托车等交通工具。安全性方面，想要开启BLE 智能锁，必须输入正确的用户密码，起到了防盗的功能，并且可以通过手机应用查看BLE 智能锁的状态，如电量等。 为了实现本次应用，需烧写BLE 协议栈软件库及应用程序到RL78/G1D 演示板，并安装相应APP 到Android 智能手机，从而通过BLE 功能实现手机对智能锁的控制。其中RL78/G1D 演示板由主控板（RTK0EN0002C01001BZ 套件）和外围板（电源电路，电机控制电路等）组成。 BLE 智能锁系统截图: BLE 智能锁APP 截图，见“相关文件”自行下载: BLE 智能锁演示板和APP 主控界面（开锁）: 整个设计 BLE 智能锁资料截图: 蓝牙低功耗 BLE 智能锁 PCB源文件截图，用AD或者PADS9.5直接打开: BLE 智能锁程序源码、APP截图:
