Telink-泰凌微电子 B91通用开发套件 蓝牙BLE测试
最近被下载这个问题一直在下载不进开发板问题所困扰，总是提示下载不成功，最终是板子IC虚焊引起下载不成功，最近五天一直在找这个问题，现在下载程序时，是用手按住IC下载，现在今天一直是这样操作，感觉 有点很高无懒。
下面我上的代码注释就少写一点，我想这两天多写两篇测评。
首先在官网下载DEMO,B91M_SINGLE_BLE_SDK
打开这个软件（Telink_RDS_v323）--文件---导入上面压缩包中的工程，具体细节略过，请看上两篇帖子。
编译一下，叫构建项目。再下载到开发板中。
下面我们来看一下代码：初始化这些我就不弄上来了，那个就略过。
首先是蓝牙的名字：
const u8 tbl_scanRsp [] = {
0x08, 0x09, 'm', 'e', 'i', 'y', 'a', 'o', 'w',
};
下面是功能的相关定义，可以见app_config.h这个文件。

下面上电脑连接的操作步骤：
首先电脑如果有蓝牙功能，那就可以当蓝牙来用，在设备中找到蓝牙和其它设备，再添加蓝牙。
连接成功后的蓝牙，这里名字我没有完全改过来，所以连接时与连接成功的名字显示不一样。
下面是手机连接蓝牙与信号
下面上传电脑与手机操作时的视频，有点远，有点小，看的不是好清楚
