A note on security: Using a timestamp as a 'unique' and 'unpredictable' session ID is generally considered pretty insecure, as timestamps tend to have little entropy and are easily predicted/extrapolated by an adversary. For better security, session IDs are usually long (e.g. 128 bits) fully ...

Solution here viewtopic.php?t=44196

So, i found solution and it works.

0) #define AUTH_COOKIE_KEY "auth-token"

1) Create struct

typedef struct
{
uint64_t timestamp;
uint8_t fd;
} um_webserver_token_t;

static um_webserver_token_t auth_token;

2) Create basic methods, that operates with token

/**
* Get user token from ...

teletypeguy - thank you!

https://github.com/espressif/esp-idf/issues/15450 I also open new issue on github.

In the meantime, I'll double-check the schematics and check how your code works on my device.

If the hardware is working with arduino framework, but not idf, then you are correct that it is likely software-related.

Exactly! That's what I'm talking about.
Thanks for the example. I'm going to try it now and I'll come back with an answer.

Can you tell me how your card is connected to esp32 ...

Once again, I reconnected everything with short wires using different ready-made SD card modules. The card was powered via AMS1117 3v3 (not from ESP32).

I conducted a comparative analysis of running programs on the Arduino IDE and on the ESP-IDF

Well, the cards do not work via the ESP-ID example ...

It almost looks like mosi and miso are mixing somewhat -- do you have the 3.3V connected to the pullups?


I checked and pullup all the lines with resistors, checked and pullup each one in turn. In different ways. I wrote about it. Thanks for the help. Do you have any idea why the signals are ...

Your scope signals are so bad that I am surprised you got any sd-cards to work. Whenever you see logic signals not at proper levels there is something wrong. It almost looks like mosi and miso are mixing somewhat -- do you have the 3.3V connected to the pullups? I did this once and then you have ...

In the logs of the working / failing card, the main difference I see, is the error code returned by the library when it tries to get the characteristics of the card. While the working card responses with 0x106 which means not supported, the failing card case shows 0x107 which means timeout ...

Friends, do you have any idea what's wrong with sd cards or their software support? Check out the pictures above that I sent. So far, the problem has remained the same.
