I have ESP32s networked with ESP-NOW. The ESP32 send and receive data from a central hub. This central hub is connected to a server computer via USB. The computer sees the ESP32 connection as a serial port. The computer is running Windows 10 or 11 with a website hosted by IIS. I ...
首先定义tcp服务器的端口号,udp目标接收方的端口号,一个全局变量以保存本地IP地址: #define UDP_SERVER_PORT 8848 #define BROADCAST_PORT 8080 #define BROADCAST_INTERVAL_MS 5000 #define DEVICE_NAME "ESP32_SERVER" esp_ip4_addr_t ip_addr; 1. 2. 3. 4. 5. 6. 在自定义的wifi事件回调函数中获取...
In a first approach, I wanted to make my webserver sends a POST request to my ESP32 which would store, in a variable, the data received. First question : Is it possible to send POST request to an ESP32 from a webserver ? Second question : Do you have any other idea, how to send...
Everytime the server sends data, it receives the OK and SEND OK replies. However, if we place the client out of range from the server, the server freezes waiting the SEND OK or SEND FAIL reply. At this point, I am not able to send any data to the esp-32. It takes about 3 ...

httpd_start(&server);8. 发送响应 在URI处理函数中，可以使用httpd_resp_send()函数将响应发送回客户端。该函数需要传入一个httpd_req_t结构体作为参数，该结构体表示HTTP请求和响应。例如，在上面的hello_get_handler处理函数中，可以使用httpd_resp_send()函数将“Hello, World!”字符串作为响应发送回客户端：s...
httpd_thread 函数中的http_server函数就是http服务的核心逻辑。 /* The main HTTPD thread */staticvoidhttpd_thread(void*arg){intret;structhttpd_data*hd=(structhttpd_data*)arg;hd->hd_td.status=THREAD_RUNNING;ESP_LOGD(TAG,LOG_FMT("web server started"));while(1){ret=httpd_server(hd);if(re...
