如果靠 UDP 本身协议是无法获知对方通信中断了,只有靠 UDP 上层应用层加处理逻辑判断,类似你说的心跳包。

Re: udp的发送接收端口如何设置
详细请参考 udp_client/udp_server 示例(https://github.com/espressif/esp-idf/bl ... ls/sockets)。设置发送接口通过 sendto 发送的地址决定,设置接收端口通过 bind 决定。

Re: ESP8266_RTOS_SDK中没有esp_log_system_timestamp?
ESP8266 目前还不支持 esp_log_system_timestamp,你可以先安装 IDF 的写法移植过来。当前 ESP8266 master 版本和 tag v3.4 版本是与 IDF 最接近的版本,可能文档上还需要再完善,但是功能上是向 IDF 靠齐了。

Re: 如何能在不使用HTTP服务器的情况下进行OTA升级
使用 HTTP 也只是一种传输方式,最终的目的还是获取到固件。你使用上位机发送也是可以的,接收到固件写入的流程你可以参考 https://github.com/espressif/esp-idf/bl ... _example.c。

Re: 关于UDP 通信中断监听
UDP 是无连接的传输,无法感知通信是否中断。请问一下您的使用场景是什么?
