https://devzone.nordicsemi.com/f/nordic-q-a/66167/read-serial-data-sent-by-a-pc-through-usb-to-nrf9160-dkHello everyone, I have a Python script on my PC sending data through serial port COM5. I want to know if it would be possible to read the data sent from the PC on the nRF9160DK, which is connected in the COM5 port of my PC.

If you open the Device Manager--&gt;Ports you can see what COM ports your computer uses for these.</p> <p>The COM port used on the computer is not consistent and the PC will choose whatever is available.&nbsp;In <a href="https://devzone.nordicsemi.com/f/nordic-q-a/6220/relating-com-port-name-and-segger-id">this ticket</a>, a customer has uploaded a python script that gets the COM port based on the Segger ID. In <a href="https://superuser.com/questions/851192/change-com-port-number-programmatically">this link</a> it is discussed how to change this COM port programatically, however,&nbsp;it does not seem like this is recommended.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
