【XR806开发板试用】将“米家蓝牙温湿度计2”的数据上传到阿里云

IoTxr806”星辰“CPU

一、开发环境搭建

  • 开发平台

    • Windows 10
    • WSL-Ubuntu-20.04

  • 适配 OpenHarmony 的 xr806 SDK

    • 使用 repo + https 从 gitee 获取源码
repo init -u https://gitee.com/openharmony-sig/manifest.git -b OpenHarmony_1.0.1_release --no-repo-verify -m devboard_xr806.xml
repo sync -c
repo forall -c 'git lfs pull'
  1. OpenHarmony\_1.0.1\_release 分支里的 devboard\_xr806.xml 中，跟 xr806 相关的部分仓库路径已经失效，所以需要从临时仓库获取xr806的代码
# device/xradio
cd device
git clone https://gitee.com/moldy-potato-chips/devboard_device_allwinner_xr806 xradio

# vendor/xradio
cd vendor
git clone https://gitee.com/moldy-potato-chips/devboard_vendor_allwinner_xr806 xradio
  • 工具链、LLVM、hb以及其他必要的库和工具，参考鸿蒙的开发文档
  • 遇到的问题：

在 WSL 中编译时，遇到了 mkimage  程序无法执行的问题，原因是 mkimage 是 32-bit的程序，最终按照一篇文章的方法解决了该问题，文章链接如下：https://www.cnblogs.com/TatuCz/p/10330820.html

二、实现思路

  1. 所需硬件或者服务

    • 米家蓝牙温湿度计2代 title=
    • XR806开发板
    • 阿里云物联网平台
  2. 实现框图 title=
  3. 程序实现流程 title=

三、代码实现
