spiffs | Wear-leveled SPI flash file system for embedded devices

I'm developing on an ESP32 with vscode and the ESPAsyncWebServer and Wifi libraries. I'm tring to make my own wifi manager, so I'd like to put some function in a class, but I've some trouble to point to member functions.

I have this definitions without class:

I'm writing a webserver for an ESP32, written primarily in C and using platformio and ESP-IDF on VSCode. With a single client, the server works great, but as soon as I try to load a page on more than 1 device (doesn't matter if all the same page or different), everything slows to a crawl. I can see the page requests arriving on the server nice and snappily, but the pages won't load/be sent for up to a minute.

When this is happening, the server seems to favour an arbitrary device; my android phone, for example, will load pages at normal speeds while my PC and iPhone will be stuck, or on another occasion the PC will be loading fast and the other two devices stuck. This makes me wonder if it's related to my server/socket handling task, but ESP-IDF is such a tangled web of dependencies I'm not sure where to begin looking. I've made a post on the Espressif forum, but haven't had any responses yet. It's not the wifi connection alone, as if I connect all 3 devices but only access the webpages from one, that device still loads everything fine.

Updates:

07/02 - I'm more and more convinced that the culprit is the socket task, as it doesn't seem to allow for multiple sockets simultaneously; after accepting one it handles everything for that one socket before looping back and accepting another one.

08/02 - I modified tcp_server_task to start a new task for each socket (below is now the modified function and additional task), but this if anything made things worse, leaving me more confused than before.

09/02 - I tried increasing the backlog argument of listen() from 1 to 32, this also made no difference.

Attempted (failed) solutions now include:

• Setting keepAlive to 0

• changing dest_addr_ip4 from INADDR_ANY to 192.168.4.1, the desired address for devices to connect to

• pinning the socket handling task to a different core to the tcp_server_task

• adding vTaskDelay(pdMS_TO_TICKS(x)) at various points with various values of x

Stuck devices are still consistently loading simultaneously after however long it takes (usually 30 to 60 seconds, sometimes longer)

10/02 - I forgot to mention, the ESP has bluetooth enabled as well, as we want users to be able to control stuff over both wireless methods.

socket handling task(s):

I have folder contain n txt file(files have numeric values) I need to read these files and save the file contains in array. How can I read the contents of the first file1 in the array and then clear the array ,and then read the second file2 in the same array and so on?

I'm trying to read txt file (has numeric values) line by line. I used SPIFFS and I used this function

I have a piece of code where i read a CSV file and prints it contents. Now the issue is that I want to run my code on ESP32 and because of some limitations of micropython I can't upload my file in the spiffs storage. So is there any way I can store the csv file content in the code itself instead of reading it from the outside?

My code:

I'm codding for Arduino (ESP8266), and have to read a string from a file, to use it. I don't know how long is that file, so I have to create a char* and pass it to the readConf function so that malloc decides for the memory size.

I feel like this question has been asked a bunch of times, but none of the answers I have found seem to be working for me. I'm extremely new to CMake and C/C++ as I come from the world of Java, and am struggling to understand cmake and how it works.

Anyways, basically I have the folder structure below. This is an esp-idf project, so I don't know if that has anything to do with what I'm running into.

I'm trying to port the file_serving example to use HTTPS.

I've attempted to move the spiff file server functionality to the existing https_server example inside esp-idf but I get the error: httpd_server_init: error in creating ctrl socket (112)

I realize that this is probably not the easiest way to do it and instead I should work on re-writing the original file_serving example code to use https instead. The function to start the server is in the file_server.c:

I want to create a function for an ESP2866 microcontroller that saves an arbitrary number of configurations to a config file on the filesystem. I found a way to do it and I was wondering if it could be any better.
