OTA_HTTP
功能概述
此应用程序是使用 WM IoT SDK 进行设备空中（OTA）固件升级功能的全面示例。它演示了连接到 Wi-Fi 网络、启动 OTA 更新以及处理更新过程中的各种状态的过程。
环境要求
创建固件 HTTP 服务器，可使用 Python 进行创建
python -m http.server [port]，示例如下：python -m http.server 8080
通过
wm.py menuconfig或wm.py guiconfig配置EXPLLE_WIFI_SSID、EXPLLE_WIFI_PASSWORD和OTA_IMAGE_URI该工程使用到的分区表必须包含
app_ota分区，分区表可参考分区表机制
编译和烧录
示例位置：examples\ota\ota_http
编译、烧录等操作请参考：快速入门
运行结果
成功运行将输出如下日志
