With Thingy53 in the Lesson 6 Ex 2 of the nRF Connect SDK Fundamentals course, the VSC window Connected Devices says: no devices found

[p143]

Hi All.

Trying to complete Lesson 6 Exercise 2 from the course nRF Connect SDK Fundamentals made by the DevAcadeny, I connected the Thingy53 to my computer through USB-C (Supply + Data), using nRF Connect SDK v2.7.0, VSC as IDE, Firmware v2.7.0, and nRF Connect for VS Code Extension Package. Everything goes fine till I complete the Build. At this point, no matter if I try with Lesson 2 or with Lesson 2 sol, the window Connected Devices shows the notification "no devices found."
With the rest of the lessons, I used an nRF52840dk developing kit and never had this problem, so I wonder if, in this exercise, the data link between the PC and DK board doesn't use the USB interface, but rather another connector (SWB, TWI ?).
Any suggestion? Thanks.

Juan

(I have seen the case from Johanan, but he uses a different HW, and the comment is from almost 2 years ago...

Hello Juan, 

Note that the Thingy:53 does not have any onboard debugger as with our development kit, e.g. nRF52840DK, it will therefor not be listed. This is explained in step 13 of exercise 2 in Lesson 6 of the nRF Connect SDK Fundamentals course. 

You need to power of the Thingy:53 before you put it in DFU mode by pressing SW2 while switching SW1 to the ON position. You should then be able to program the Thingy:53 using the Programmer app in the nRF Connect for Desktop.

Let me know how that works for you

Kind regards,
Øyvind

Hi Øyvind.
Sorry for the delay.

Following your instructions, I obtained your anticipated result: a "Completed succesfully" message.
Despite this encouraging result, the CONNECTED DEVICES Window kept showing the old message, "no devices found," even after pressing the refreshing button.
Also, I checked the Devices Manager tool, and with the thingy53 connected, the paragraph Ports (COM and LPT) Serial USB (COM 15).
As a result, still without connectivity with the commands console, I couldn't complete the exercise.
Any suggestion?

Thanks.

Juan

Can you please provide a screenshot of what window you are referring to?

Here is how it looks on my side.

Hi, Øyvind.

That's what I was referring to by "CONNECTED DEVICES Window":

Summarizing: using the programmer from the nRF Connect for Desktop, I flashed the application to Thingy53 seamlessly, but going back to VSC, there is no COM serial port showing up, so I can't visualize the console.

Thanks for your help,

Juan

Yes, that is correct as the Thingy:53 does not have an onboard debugger, and the connected devices will only show boards with an onboard debugger, ref. https://academy.nordicsemi.com/flash-instructions-for-the-thingy53/

That said, you should be able to open the Serial Terminal in VS Code in the VS Code terminal. Click on Terminal in menu --> New terminal 

Then clickon the down arrow next to the + sign and add nRF Serial Terminal.

This should give a dropdown menu from the search bar in the top of VS Code, from here you should be able to select the COM port of your device and connect.

Kind regards,
Øyvind

Hello, Oyvind.

I implemented it seamlessly once you explained how to get the console working. Thanks.

(Note: if you write this in the course documentation, I reckon many people would appreciate it)

I couldn´t upload a screenshot showing the system working. The JPG image was 320x172 pixels, and I tried both writing the path to the image and dragging it. Maybe the next time ...

Kind Regards,

Juan
