-3. 需要把文件BCM43430A1.hcd放到文件系统中去。
+BTstack is [BlueKitchen's](https://bluekitchen-gmbh.com) implementation of the official Bluetooth stack.
+It is well suited for small, resource-constraint devices
+such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint.
 
-4. 程序烧入之后，输入命令bt_stack_port_main可以启动蓝牙
+Targeting a variety of platforms is as simple as providing the necessary UART, CPU, and CLOCK implementations. BTstack is currently capable of connecting to Bluetooth-modules via: (H2) HCI USB, (H4) HCI UART + TI's eHCILL, and (H5) HCI Three-Wire UART.
 
-5. 看到如下的log，说明蓝牙已经起来了
+On smaller embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS).
+If a RTOS is already provided, BTstack can be integrated and run as a single thread.

+**Protocols:** L2CAP (incl. LE Data Channels), RFCOMM, SDP, BNEP, AVDTP, AVCTP, ATT, SM (incl. LE Secure Connections).
 
-   7.连上该设备之后，打开notification，可以看到gatt_counter计数器在增加。
+**Profiles:** GAP, IOP, HFP, HSP, SPP, PAN, A2DP, AVRCP incl. Browsing, GATT.

+**GATT Services:** Battery, Cycling Power, Cycling Speed and Cadence, Device Information, Heart Rate, HID over GATT (HOG), Mesh Provisioning, Mesh Proxy, Nordic SPP, u-Blox SPP. 
+
+GATT Services are in general easy to implement and require short development time. For more GATT Services please contact us, or follow the [implementation guidelines](https://bluekitchen-gmbh.com/btstack/profiles/#gatt-generic-attribute-profile).  
+
+It has been qualified with the Bluetooth SIG (QDID 110883) for GAP 1.1, IOP, HFP 1.7, HSP 1.2, SPP 1.2, PAN 1.0, A2DP 1.3, AVRCP 1.6 profiles and
+GATT, SM of the Bluetooth Core 5.0 specification. For information on MFi/iAP2 support, please <a href="mailto:contact@bluekitchen-gmbh.com">contact us</a>.

+## 4. Attention
+
+​        On RT-thread system，only support AP6212 currently（base ART-H750 board）。We will support other control in future.

+# RT-Thread_BTstack
+
+## 1. 介绍
+
+BTstack 软件包是RT-Thread 基于 [btstack](https://github.com/bluekitchen/btstack) 开源蓝牙协议栈的适配，该协议栈支持多种蓝牙卡片，非常适合用于小型嵌入式蓝牙设备，支持几乎所有的主流的蓝牙卡片，支持无RTOS操作。
+
+## 2. 主要支持的Profile和Protocol
+
+**Protocols:** L2CAP (incl. LE Data Channels), RFCOMM, SDP, BNEP, AVDTP, AVCTP, ATT, SM (incl. LE Secure Connections).
+
+**Profiles:** GAP, IOP, HFP, HSP, SPP, PAN, A2DP, AVRCP incl. Browsing, GATT.
+
+**GATT Services:** Battery, Cycling Power, Cycling Speed and Cadence, Device Information, Heart Rate, HID over GATT (HOG), Mesh Provisioning, Mesh Proxy, Nordic SPP, u-Blox SPP. 
+
+GATT Services are in general easy to implement and require short development time. For more GATT Services please contact us, or follow the [implementation guidelines](https://bluekitchen-gmbh.com/btstack/profiles/#gatt-generic-attribute-profile).  
+
+### 3. 许可声明
+
+BTstack 非商业用途是免费的。但是，对于商业用途，<a href="mailto:contact@bluekitchen-gmbh.com">请联系BTstack官方</a>关于你的项目以获得商业合作。
+
+## 4. 注意事项
+
+​        BTstack支持很多蓝牙卡片，目前在RT-thread系统上，只支持AP6212卡片（基于ART-H750开发板），后续会支持更多蓝牙卡片。
+
+## 5. 目录结构
+
+本目录基本参考 [btstack](https://github.com/bluekitchen/btstack)的目录创建，适配的代码放在rtt_adapter上面，其余代码基本和源BTstack代码一致，如需更新可以自行从github上更新
