I, too, faced such a need!
Any help!
How to change device name?

I figured it out, I had to remove the check. if (data->op_code == 0x08 && data->data_len == 2) { sendUART("OK!", "WS Received Closed Message", NULL); } else { parserWS(data->data_len, (char *)data->data_ptr); } And I installed this construction (checking for more than 8 because the shortest JSON obj...

I read it. Now another problem arose. I send 3-5 requests to the server and then get 3-5 responses at once. I need to receive responses for every request. My complete code: esp_err_t webSocketInit() { if (xTaskCreate(taskWebSocket, "taskWebSocket", 4096, NULL, 6, &xHandleWebSocket) != pdPASS) { send...

Hello everyone! I am trying to use the Websocket Client example. I have no idea how to get a normal string. I see that I can get a pointer to a string and its size. But I am not getting anything. void parserWS(const char * data, int len) { char * buffer; buffer = (char *) malloc(len + 1); if (buffer...

Tell me how to work with UDP Client correctly? I want it to stop if it works like AP or APSTA. Delete the task FreeRTOS at night and then re-create it, or what's the right way? I am also interested in the operation of WebSocket, I cannot stop it (esp_websocket_client_destroy (client)) through the WE...

Resolved!
Extra break; installed in the code.

Faced strange application behavior. I send broadcasts to the network to find other devices. They are sent periodically by setting a timeout time for int len = recvfrom (sock, udpcBuffer, sizeof (udpcBuffer) - 1, 0, (struct sockaddr *) & source_addr, & socklen); The first time I send a request, every...

Thanks for the advice! But I still haven't figured out how to work with select () I used advanced settings struct timeval read_timeout; read_timeout.tv_sec = UDPC_RESPONSE_TIMEOUT; //... setsockopt (sock, SOL_SOCKET, SO_RCVTIMEO, & read_timeout, sizeof read_timeout); It works, but I don't know if it...

I repeat, I've already done almost all the modules. I used ready-made examples and created a task in FreeRTOS for each module. I just wanted to know if there are any other approaches to writing applications. This post is not specifically about my requirements, but as a general approach to writing a ...

Hello everyone! I would like to get some tips on how to create a complete firmware for ESP32. It is the general concept and used approaches to programming using ESP-IDF. There is a lot of documentation and examples too, but they do not show the whole concept of building a correct application. Just b...
