1、功能说明
    蓝牙BLE数传服务（rdts)例程，使用128bit UUID。BLE主机连接设备后，下行数据将透传到USART1，USART1收到的数据将透传到BLE主机
2、使用环境
    软件开发环境：  KEIL MDK-ARM V5.24.2.0
    硬件环境：      基于N32WB031_STB开发板
3、使用说明
    系统配置；
        1、时钟源：HSI=64M
        2、调试串口使用的是LPUART（PB1/PB2），波特率是115200，8bit数据位，无校验位，1bit停止位，无流控。
        3、数据串口使用USART1（PB6/PB7），波特率115200，8bit数据位，无校验位，1bit停止位，无流控。
        4、蓝牙BLE名：NS_RDTSS
        5、LED1开机即亮，LED2指示连接状态，蓝牙连上后亮
    使用方法：
        1、编译后烧录到开发板
4、注意事项
    由于程序会进入sleep模式，则SWD将不能访问，请按RESET按钮后，在一秒之内执行烧录程序步骤。
