Problem connection to Thingy:53

[AndersB]

Hi,

I recently received my Thingy:53, Started to connect it via USB to my desktop computer (windows 10)

Then started nRF Connect for Desktop v4.0.0 and then selected nRF Connect Programmer Official, v3.0.5.

After that SELECT DEVICE and selected Application Thingy:53 from the list. Now I receive log:

09:29:08.936 Using nrf-device-lib-js version: 0.5.0
09:29:08.936 Using nrf-device-lib version: 0.13.11

Last log message in red.

What is wrong?

Hi,

Are you able to put the thingy in bootloader mode?

Press and hold SW2 while you power the Thingy53 OFF and ON again.


It should look like this(above picture) instead of saying Application Thingy:53


SW2 is located under the cover right next to the "big" button. 



Then you should be able to program the device over USB with the programmer app. 

Regards,
Jonathan

Yes, I finally realized that I pushed the wrong button. The right one was not big. So that's OK. But I have a question about Thingy:53 in VSCode. I can't see it under connected devices and I know that Thingy:53 is in bootloader mode.

Any idea what's wrong?

I am newbie in this field and while getting starting I had the same issue. From my research in the devzone I (maybe we) do need to connect my thingy53 through the UART cable to the "debuguerr" piece in the kit. Am I correct JONATHAN LL ?

[JONATHAN LL]

Sorry for the slow response JuniorDev , AndersB 

If the idea is to just get UART communication then a single USB cable from the computer to the Thingy53 USB port is sufficient. 

What version of the VS code and the nRF Connect for VS code are you using?

If you want the Thingy53 to show up under the "connected devices tab" in the nRF Connect for VS Code interface on VS Code then you need an external debugger. 

It will look like this when an external debugger us used:

This is with a nRF5340DK as the external debugger(the ID of the nRF5340 DK onboard debugger is highlighted in yellow). Similar to the setup show here:https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/working_with_nrf/nrf53/thingy53_gs.html#updating-through-external-debug-probe 

If you just connect the device to with a single usb cable regardless of if it is in the Application mode or Bootloader mode it will look like this:



So if you do not have any external debugger then you need to build the project in VS code then use the Programmer app to program the Thingy53 by moving the generated .hex files over to the programmer app and use the write function when the device is in bootloader mode. 

Here is the guide on how to do it over USB https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/working_with_nrf/nrf53/thingy53_gs.html#updating-through-usb

OK, I understand.

Thanks
