HI 

 I need help to create a UART communication between nrf5340 & esp32.

Thanks & Regards

Hi Navin

Could you be a bit more specific regarding what you need help with?

I made an example some time ago showing how to use the UART async driver in the nRF Connect SDK, and you could start by taking a look at that:
https://github.com/too1/ncs-uart-async-count-rx

In order to set up a separate UART for use with your ESP device you can create an overlay file, that sets up another UART in addition to the one normally used for logging, and refer to that in the example instead of UART_0. 

If you need help with this just let me know, and I will provide an example. 

Best regards

Hi Torbjorn

I can communicate with the  esp32. But the output was shown as an ASCII value like shown in the below image

Thanks & Regards

Hi Navin

What kind of terminal program are you using?

Could you try it with another terminal program, like Tera Term, Putty, or RealTerm, and see if it looks normal?

Best regards
