I have two (possibly related) questions:

1) In the ESP-IDF /examples/sta2eth code, I must ensure that I `#define MODIFY_DHCP_MSGS 1` at the beginning of /main/ethernet_iface.c. If I don't do this, my target ESP32's (or ESP32s3's) eth0 interface will not be assigned an IPv4 address, and I will not ...

Thanks to all for clearing up my confusion. I see a pathway ahead.

Thanks.

Sounds sensible. I suspect I'll have to see how often the tools break. I've noticed it's not too bad with the main frameworks (the ESP-IDF frameworks), but I've been struggling to build examples from the likes of https://github.com/espressif/esp-iot-bridge and https://github.com/espressif ...

Hello,

I am trying to install several different versions of the ESP-IDF framework in the VS Code IDE. This seems fairly trivial. I am installing them in different directories, naturally.

However, after each ESP-IDF framework download, I am asked whether I want to install the corresponding toolsets ...

Hi there all,

Well I've been at this a few days and it's been endless frustration! However, I think I'm gradually ironing out the issues. I believe I have identified the problem area (I hope, anyway). For reference, I should mention that I am using VS Code as my IDE with the official ESP-IDF ...

Thank you Mr MicroController! You have cleared up some fundamental things for me.

If we look in uart.c, which I think I'm correct in saying lives in the ESP-IDF API layer underlying the Arduino-esp32 API, we find functions like:
esp_err_t uart_get_buffered_data_len(uart_port_t uart_num, size_t *size)
{
ESP_RETURN_ON_FALSE((uart_num < UART_NUM_MAX), ESP_FAIL, UART_TAG, "uart_num ...
