第1节 http本地空中升级

1.1打开服务器

官方编译链内 Python 有一个内置的 HTTP 服务器，可以直接使用它；以esp-idf-v3.1.4\examples\get-started\hello_world作为需要更新的固。

打开mingw32官方编译链，输入以下指令：

 

cd $IDF_PATH/examples/get-started/hello_world //进入 helloworld 路径make                                              //编译

cd build                                    //进入编译文件.bin 目录python -m SimpleHTTPServer 8070               //运行 http 服务器（本地）

   

 

服务器运行后， 构建目录的内容可以通过网址 http://localhost:8070/ 浏览到。升级期间需要保持服务器开启，升级完成后如果想要关闭服务器关闭这个编译链即可。

1.2修改官方例程

1.2.1 修改库文件esp_https_ota.c

修改库文件esp-idf-v3.1.4\components\esp_https_ota\src下的esp_https_ota.c内容：注释下图两个红框中内容，这两处是https空中升级用到的。

 

1.2.2 修改例程simple_ota_example.c

接下来修改例程，这里使用esp-idf-v3.1.4\examples\system\ota\simple_ota_example

修改其main文件夹下的simple_ota_example.c中内容：修改替换如下图

 

最后修改文件配置，另外再打开一个mingw32官方编译链修改simple_ota_example

配置，输入以下指令：

 

cd $IDF_PATH examples\system\ota\simple_ota_example //进入路径

make menuconfig                                        //进入配置

 

1.2.2.1 修改OTA分区为双 OTA 分区

首次进行 OTA 升级时， OTA example 向 OTA_0 分区烧录目标 App， 并在烧录完成后， 更新 OTA data 分区数据并重启。系统重启时获取 OTA data 分区数据进行计算， 决定此后加载 OTA_0 分区的 App 执行（而不是默认的 Factory App 分区内的 App） ， 从而实现升级。同理， 若某次升级后 ESP32 已经在执行 OTA_0 内的 App， 此时再升级时， OTA Demo 就会向 OTA_1 分区写入目标 App。 再次启动后， 执行 OTA_1 分区实现升级。 以此类推， 升级的目标 App 始终在 OTA_0、 OTA_1 两个分区之间交互烧录， 不会影响到出厂时的 Factory App 固件。

 

1.2.2.2 修改下载端口 port

此次的example下载是通过串口下载的，修改配置文件中下载端口为自己下载器的端口。Port会应不同电脑不同下载器而不同，写入自己实际的COM口，我的是COM6。

1.2.2.3 修改WiFi账号密码以及url

WiFi账号密码是ESP32启动后联网的，由于http模式是本地模式，所以WiFi账号和密码需要和第一节打开服务器的电脑在同一个局域网内。url就是ESP32 连接上服务器之后要去访问的目标地址。

WiFi SSID和WiFi Password填上你电脑连接的WiFi账号密码，如果你的电脑是网线联网这里只要保证填入的WiFi账号密码是该网关下的无线网络即可，url马赛克部分192.168.xx.xx是本机IP,可通过运行cmd输入ipconfig查看，这里填上自己本机ip 。

以上三步修改均需要单步保存，即选择 <Save> 。至此修改就全部完成了，单步全保存之后一路点击 <Exit> 推出即可，接下来就是编译下载了。

1.3 编译下载

Windows下的编译非常之慢，由于上面修改了配置文件所以编译是更加慢的。输入 make 编译，大约需要5-10min，耐心等待一会。

编译成功后输入 make erase_flash flash 全擦除并下载。

 

1.4 实验验证

编译下载通过之后，就可以运行了，等待ESP32 成功联网之后就开始连接服务器了，ping通服务器之后就开始下载 hello-world.bin ,这个过程需要3min左右等待日志打印结果即可。以下是日志文件：灰色部分是simple_ota_example例程的日志文件，青色部分就是hello-world例程的日志文件。
