Hi, did you make any changes to the example? I am not able to recreate the error you're seeing. Did you place a jumper on P2.1 and P2.2, and not on RXD and TXD on the board?

You need short P.2.1 and P.2.0 in order for the loopback test to work. I edited my answer with the image showing the jumper placement.
