蓝牙驱动实验板参考源码，主要是HC05的板子，其它相关芯片的数据透传也一样的可以参考该代码-Bluetooth driver test board reference source, mainly HC05 board, other related chips pass through the same data can refer to this code

1,通过STM32的USART2连接ATK-HC05蓝牙模块,检测并显示蓝牙模块的状态. 2,通过KEY0按键可以开启/关闭定时向ATK-HC05蓝牙模块发送数据(ALIENTEK HC05 xx)测试蓝牙模块的数据发送. 3,可以通过WK_UP按键设置ATK-HC05蓝牙模块的主从工作模式.-1, ATK-HC05 Bluetooth module connected through the STM32 USART2, detects and displays the status o

该部分程序为stm32f103与蓝牙hc05进行蓝牙信号传输的程序，经测试有效-This part of the program for the stm32f103 hc05 Bluetooth Bluetooth signal transmission program, tested and effective
