Hi

Thank You for providing the steps on how to integrate Arduino Library with IDF.
I have followed the steps but I am always getting this error message.

../components/arduino/cores/esp32/esp32-hal-uart.c:329:19: error: implicit declaration of function 'uart_get_tx_buffer_free_size'; did you mean 'uart_get_buffered_data_len'? [-Werror=implicit-function-declaration].

What can be the possible error?
Is this because of any liking issue.

Regards
Anurag

Not too sure. But here is a hint.

Version of ESP32 Arduino Core should be same as ESP-IDF 5.x (released version).
Current Arduino master branch version is not for ESP-IDF 5.x I believe.

Can I use https://github.com/espressif/arduino-esp32/tree/idf-release/v4.4 ? Instead?
Because I am using esp-idf version 4.4 .

I have tried the above comment but it does not work.
Can You help me how to achieve the same if I am using esp-idf version 4.4?

I am not too sure. If you are using 4.4 it should work. I am on IDF 5.1 so cannot test it.
Maybe you are missing a header include?

Here is the error lines
