Why you don't want to use callback? Using `mac->receive` is not designed to be called from user code.

Because I only need to capture the first frame.

It's pretty straight forward, just register your callback function to the Ethernet handler. See examples: https://github.com/espressif/esp-idf/blob/master/examples/network/simple_sniffer/main/cmd_sniffer.c#L300 https://github.com/espressif/esp-idf/blob/master/components/esp_eth/test_apps/main/esp_e...

Hi, you are using the driver incorrectly. If your goal is to have your "custom" function to process received Ethernet frames, you need to register a call back function using `esp_eth_update_input_path`. Thank you for your time and attention! I am grateful. Would it be possible to document correct u...

Hello, I think the issue might be related to the buffer size you're providing. In your code, you're allocating a buffer with a fixed size of 1522 bytes using malloc(len). However, the len parameter should be initialized with the maximum buffer size you allocate and pass it to the mac.receive() func...

I'm trying to use the ESP32 Ethernet MAC receive function , but it always sets the buffer length to zero, and doesn't copy any data. I assume I'm using it incorrectly. Is there some documentation on how to use is it? #include <inttypes.h> #include "esp_event.h" #include "esp_log.h" #include "esp_eth...
