https://devzone.nordicsemi.com/f/nordic-q-a/25127/app-uart-fifo-thead-safeI&#39;m using FreeRTOS in my project and I wanted to check if the APP UART FIFO implementation is thread safe, IE I want to have a reader and writer thread. Each FIFO has a separate buffer and separate read and write pointers.
