DTM V2.00 issue in nRF CONNECT FOR desktop

[fred.feng]

Before updating to V2.00, the DTM tool can automatically detect the serial port, log has a clear indication whether it is connected to the target board, when the DTM update to V2.00, the DTM tool can not automatically identify the serial port, no way to determine whether through the serial control to the target board, log also has no prompt information。 waiting for yr reply ASAP.

Hi, 

You can check the port via Device manager as the following figure.

Hi, 

I get the same frame as your figure in the original post. DTM app doesn't list the device immediately, but it takes about 30 seconds. We are trying to improve that.   

Can you check the JLINK serial port of DK detected by the Device manager while opening the DTM app? As the figure in my first rely. In this step, we can make sure the DK connects to the pc. Then, open the DTM app.   

After selecting the DK, you will see the manual and functions are the same as the previous. 

Please let me know this can help or not. Thanks.

Hi

    I think you didn't understand what I mean.

First, before the DTM tool was updated to V2.00, the PC was connected to the target board via USB to Serial port (also known as the solid-state serial port I mentioned above);

Second: now after the DTM tool is updated to V2.00, only jlink CDC Serial can connect to DK board.

That is to say, hardware development can only use jlink CDC Serial to connect the target board.

Third: This update may increase your test DK board sales in the short term, but it is very unfriendly to product development, and some users may give up using your chip products in the long run.

So my requirement now is: what should I do if I want to use an older version of the DTM tool? In other words, what should I do if I want to connect the target board using USB to Serial port?

Hi, 

Sorry to misunderstand. We are looking into the USB port issue.
