Hi Marte,

After pressing reset I was able to see the text and communicate with the board. I guess previously the board was somehow not responding.

Hi,

The settings seem correct. In the guide the settings for local echo and local line editing are auto instead of force on, but it should still work.

Not from PuTTY, no. You will get an error if you are trying to connect to a COM port that is not in use, but by looking at your picture the connection has been opened correctly. The radio test example should print the text "Radio test example started" at the beginning though. You can try pressing the reset button on your DK after you have established the connection in PuTTY and see if it prints when it starts up.

You also mentioned that you are unsure which COM port is correct, since both COM4 and COM8 shows up. One thing you can do to find this is to run the command nrfjprog --com. This will show connected JLink debuggers and their associated serial ports. The debugger will show up as the serial number of your DK.

Best regards,

Marte

Hi Marte,

Thanks a lot for your instruction. Now I can connect without any error. While I cannot get any return when typing CLI commands. Also should I expect something like board connected successfully?

Below are my setting details. The rest pages are using default settings but let me know if you need those info.

Do you have any suggestion? Looking forward to your reply!

Hi,

From your first and last pictures it looks like your are trying to connect via RTT instead of UART. In the 'Session' settings in PuTTY you should select 'Serial', and not 'Telnet', and then add COM port and the baud rate there:
