+# 基于RT-Thread的小熊派连接华为云说明文档
+
+## 1 项目介绍
+
+- 主要功能：使用小熊派ESP8266模块连接华为云物联网平台。
+    - 设备端功能：将小熊派MPU6050模块的`xyz加速度原始值`上传至华为云平台。
+    - 云端功能：可以控制小熊派`开启上传/停止上传`数据到华为云平台。
+- 小熊派主要使用的外设：
+    - I2C：采集MPU6050的数据(i2c)
+    - UART：向ESP8266模块发送AT指令联网(lpuart1)
+- RT-Thread 主要使用到的软件包
+    - at-device：用于esp8266快速联网。
+    - mpu6xxx：用于读取mpu6050的原始数据。
+    - kawaii-mqtt：用于快速对接到mqtt服务器。
+    - cJSON：用于解析mqtt服务器下发的JSON数据。
+
+## 2 云平台配置
+
+进入华为云设备接入控制台 [华为云设备接入平台](https://console.huaweicloud.com/iotdm/?agencyId=559e6def93234d46b88a72e285cc7241&region=cn-north-4&locale=zh-cn#/dm-dev/all-product)
+
+### 2.1 创建产品
+
+![](figures/2_1_create_product.png)
+
+![](figures/2_1_create_product_suc.png)
+
+### 2.2 基于创建的产品注册一个设备
+
+![](figures/2_2_register_device.png)
+
+![](figures/2_2_register_device_suc.png)
+
+### 2.3 根据设备信息获取MQTT连接所需要的三元组
+
+我们可以通过华为云提供的官方产品帮助文档中，根据参数描述自己计算出三元组；或者我们可以使用下面的网页来帮助我们生成三元组：[Huaweicloud IoTDA Mqtt ClientId Generator (myhuaweicloud.com)](https://iot-tool.obs-website.cn-north-4.myhuaweicloud.com/)
+
+
+这里我们需要填入两个信息就可以生成三元组了
+- DeviceId：设备ID(前面注册设备的时候生成的)
+- DeviceSecret：设备密钥(前面注册设备的时候自己填入的)
+
+![](figures/2_3_mqtt_generator.png)
+
+### 2.4 查看设备接入服务器域名和端口
+
+![](figures/2_4_mqtt_host_port.png)
+
+### 2.5 获取发布和订阅主题
+
+设备使用MQTT协议接入平台时，平台和设备通过Topic进行通信。平台预置的topic列表可参考：：[华为云预置的topic](https://support.huaweicloud.com/api-iothub/iot_06_v5_3004.html)
+
+我们可以进行如下设置：
+
+设备上报属性(发布主题)：`$oc/devices/{device_id}/sys/properties/report`（需将“{device_id}”替换为所需的设备id）             
+平台下发命令(订阅主题)：`$oc/devices/{device_id}/sys/commands/#`（需将“{device_id}”替换为所需的设备id） 
+
+### 2.6 创建服务并添加属性和命令
+
+根据本项目实现的功能：
+- 设备端功能：将小熊派MPU6050模块的`xyz加速度原始值`上传至华为云平台。需要创建三个属性去显示数据。
+- 云端功能：可以控制小熊派`开启上传/停止上传`数据到华为云平台。需要创建一个命令去控制设备端。
+
+![](figures/2_6_mqtt_service.png)
+
+至此，华为云的相关配置结束。
+
+## 3 设备端配置
+
+- 小熊派主要使用的外设：
+    - I2C：采集MPU6050的数据(i2c)
+    - UART：向ESP8266模块发送AT指令联网(lpuart1)
+- RT-Thread 主要使用到的软件包
+    - at-device：用于esp8266快速联网。
+    - mpu6xxx：用于读取mpu6050的原始数据。
+    - kawaii-mqtt：用于快速对接到mqtt服务器。
+    - cJSON：用于解析mqtt服务器下发的JSON数据。
+
+### 3.1 编写一键化Kconfig
+
+根据上面的描述，可以编写一个Kconfig来一键化配置工程：
+
+```Kconfig
+config BSP_USING_MPU6050
+    bool "Enable MPU6050 to read accel data"
+    select BSP_USING_I2C
+    select BSP_USING_I2C1
+    select PKG_USING_MPU6XXX
+    default n
+    if BSP_USING_MPU6050
+        menuconfig BSP_USING_MQTT_HW_CLOUD
+            bool "Enable MPU6050 Connect to Huawei Cloud"
+            select BSP_USING_LPUART1
+            select PKG_USING_CJSON
+            select PKG_USING_AT_DEVICE
+            select AT_DEVICE_USING_ESP8266
+            select PKG_USING_KAWAII_MQTT
+            select KAWAII_MQTT_NETSOCKET_USE_SAL
+            default n
+
+            if AT_DEVICE_USING_ESP8266
+                config ESP8266_SAMPLE_WIFI_SSID
+                    string "WIFI ssid"
+                    default "rtthread"
+
+                config ESP8266_SAMPLE_WIFI_PASSWORD
+                    string "WIFI password"
+                    default "12345678"
+
+                config ESP8266_SAMPLE_CLIENT_NAME
+                    string "AT client device name"
+                    default "lpuart1"
+            endif
+
+            if PKG_USING_KAWAII_MQTT
+                config KAWAII_MQTT_HOST
+                    string "mqtt host"
+                    default "jiejie01.top"
+
+                config KAWAII_MQTT_PORT
+                    string "mqtt port"
+                    default "1883"
+
+                config KAWAII_MQTT_CLIENTID
+                    string "mqtt client id"
+                    default "rtthread001"
+
+                config KAWAII_MQTT_USERNAME
+                    string "mqtt username"
+                    default "rt-thread"
+
+                config KAWAII_MQTT_PASSWORD
+                    string "mqtt password"
+                    default "rt-thread"
+
+                config KAWAII_MQTT_SUBTOPIC
+                    string "mqtt subscribe topic"
+                    default "rtt-sub"
+
+                config KAWAII_MQTT_PUBTOPIC
+                    string "mqtt publish topic"
+                    default "rtt-pub"
+            endif
+    endif
+```
+
+> 注意，以上配置务必保证板载驱动支持`lpuart1`,`i2c1`。
+
+### 3.2 配置工程
+
+根据前面华为云得到的信息，填写对应的配置：
+
+![](figures/3_2_menuconfig.png)
+
+保存退出，直接生成工程。
+
+### 3.3 需要修改的地方
+
+这样配置后，还不能完全保证与服务器的通信连接(无法接受mqtt服务器发过来的数据)。需要修改如下两个地方：
+
+1. 修改`rtconfig.h`文件中`RT_SERIAL_RB_BUFSZ`的值。
+
+![](figures/3_3_serial_rb_bufsz.png)
+
+2. 修改`at_client.c`文件中`at_create_resp`创建的接收缓冲区大小。
+
+![](figures/3_3_at_create_resp.png)
+
