蓝牙协议栈 Bluetooth stack （English）
这是一个包含传统蓝牙跟低功耗蓝牙的协议栈，属于超轻量级蓝牙协议栈，用作学习蓝牙协议栈的人使用

在bt_config.h中配置你想要的功能，比如debug/profile enable/paring mode/chipset select/spec profile config...
前提条件：1)Keil安装 2)STM32F1/STM32F4对应的pack包 3)Download工具(我们选择的是ST-LINK)
打开工程project下的对应的stm32f10x_bb_bt/stm32f10x_bb_bt/stm32f412_bb_bt直接编译下载即可
前提条件:
1)USB转UART工具(H4 transport需要硬件流控)并且接线正确，根据丝印TX接TX,RX接RX,CTS接CTS,RTS接RTS,VCC5V,GND
2)一般需要给串口权限，比如sudo chmod 777 /dev/ttyUSB0(如果不是这个路径要修改code)
打开工程project下的linux_bt make一下，生成bt_demo后直接运行即可
目前我们的蓝牙协议栈可以在STM32F103以及在Linux跑起来,蓝牙芯片是CSR8311,支持
PROTOCOL：HCI L2CAP RFCOMM SDP AVDTP AVCTP ATT SMP
PROFILE: HFP A2DP AVRCP PBAP SPP GATT
希望会有更多的人来加入进来一起协作开发profile以及蓝牙芯片的工作。
