Thanks. Setting the Baud rate to 19200 solves the problem. Appreciate your help.

Hi,

Sorry, but I noticed that you set 9600 baud rate.

The default is 19200 baud rate with most DTM firmware. Could you check with this?

Kind regards,

Håkon

I tried both JLINK COM Ports as indicated by the Device Manager. Both don't work.

Hi,

The nRF5340-DK has two UART COM ports.

Could you try to select the other UART interface?

Kind regards,
