请问一下ATK-HC05蓝牙有何功能呢

本实验将实现如下功能： 1,通过STM32的USART2(PA2，PA3)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. 4,可以通过LCD显示ATK-HC05蓝牙模块接收到的数据. 5,可以通过USMART对ATK-HC05蓝牙模块进行AT指令查询和设置. 6,结合手机端蓝牙软件(蓝牙串口助手v1.97.apk),可以实现手机无线控制开发板(点亮和关闭LED1).
