Hello @dhruv_singh_who and welcome to the Community,

First, I apologize for my late reply.

I recommend you to take a look at steps shared in this wiki Getting started with UART and get inspired.

This article explains what is UART and how to use it through examples. In these examples USART1 is used ( PA9 for transmission (TX) and PA10 for reception (RX)).

I hope this help you.
