Error can be solved by following method though I do not recommend that, but it can implement interrupt based UART and you can have functioning code.

So, our approach was to use the function

Code: Select all

isr_register

and

Code: Select all

isr_free

which were removed in newer version of IDF, for that you have to make few changes in UART.c and UART.h:

1. copy both of above-mentioned codes from older version of SDK found from github and paste them into your files (UART.c and UART.h).
2. in

Code: Select all

uart_driver_install

function find

Code: Select all

 uart_int_alloc

function and replace it with

Code: Select all

uart_isr_register

(for this you can directly compare from both SDKs

Code: Select all

uart_driver_install

function).

Feel free to ask question.
