我正在尝试在我的代码中使用Native_ota_example的所有代码。在这种情况下，我会仔细遵循我们在native_ota示例中采取的所有必要步骤。并运行Https服务器。 我的esp32已连接到本地网络，如下所示：
976）native_ota_example：设置WiFi配置SSID MYWIFI ...
I（1076）phy：phy_version：4100，6fa5e27，2019年1月25日，17:02:06，0，0
我（1076）wifi：模式：sta（24：0a：c4：1d：34：f0）
我（1076）native_ota_example：正在准备连接
我（1096）native_ota_example：已连接
$ ota 我（11666）native_ota_example：开始使用OTA示例...
I（11666）native_ota_example：运行分区类型0子类型0（偏移量0x00010000）
我（11666）native_ota_example：正在等待Wifi事件位
$ 此事件未发生：SYSTEM_EVENT_STA_GOT_IP
请帮助
我正在使用控制台来确保OTA不会像Native_Ota_example中那样自动运行。 因此，在我的情况下，在执行过程中创建的任务实际上正在等待用户控制台输入。

预期结果：该代码应与示例代码完全一样。
实际结果：我的ESP32模块无法从Wifi路由器接收IP。
