能看到蓝牙的地址，但是搜索时找不到，请问这是什么原因导致的 ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/7/7450d0642b87dceef6584a9ff2db686e1a80e655.png) ---

你在用什么芯片和开发板？在跑哪一个 BLE 示例，用了哪些 AT command? ---

用的AmebaZ II RTL8720CM 这块，在跑 ble\_ peripheral这个，AT命令还没有用。蓝牙初始化成功之后，有显示蓝牙地址，但是我没搜到，是不是外围设备创建失败了 ---

重启后需要用 ATBp=1，BLE\_Peripheral 的示例才会开始跑 ---

嗯嗯，好的好的。那如果我不使用AT命令，能让ｂｌｅ＿ｐｅｒｉｐｈｅｒａｌ跑起来吗 ---

SDK 默认的 BLE 示例都是需要 AT 命令的，要让它自己跑，就需要改代码 ---

我的ble——peripheral已经跑起来了，我准备接着搞bt\_mesh这块，请问这块有什么资料可以看的吗 ---

你是在用 [GitHub](https://github.com/ambiot/ambz2_sdk) 上的 SDK 吗？还是 NDA 的？ ---

好像是NDA的，我看这个文档上有文件水印 😂 ---

如果在 `\component\common\bluetooth\realtek\sdk\example` 有看到 mesh 的示例，那就应该是 NDA 的，mesh 应该没有加入 github 上的 SDK. UM0203 是专门解释 BLE mesh 的文件，应该是看这个 ---

嗯嗯，好的好的，找到了
