[Chayim]

Why is my nRF52840 not detected in connected devices in Visual Studio ? I installed everything also latest version of the nRF Command Line Tools

Windows 11 latest updated

Hi,

Do you have a nRF52840 Development Kit or nRF52840 Dongle?

Regards,

Thanks. Already read this on another request that the dongle is not supported 

[Sigurd Hellesvik]

The nRF52840 Dongle is using a bootloader.

VS Code detects devices connected via a debugger (for example DKs).

To program the nRF52840 Dongle, I recommend the nRF Connect for Desktop programmer app.

Ohh yeah I am using that app thanks for the quick reply. By th way do you have sample for zigbee light switch for nrf52840 dongle?

[Sigurd Hellesvik]

While the ZigBee light switch sample sample is not offiically tested for the nRF52840 Dongle, I beleive it should work.
Maybe some changes are needed, but it should not be too much.

Let me know if you get issues running this sample on the Dongle

If I only use the nRF Connect for Desktop Programmer, how can I debug the nRF52840 dongle? Could erasing the bootloader perhaps offer a solution? And how to erasing bootloader.

Hi Genfeng.

The nRF Connect for Desktop Programmer app does not support debugging.

To debug the nRF52840 Dongle, you need an external debugger. This can for example be a Jlink debugger or one of our Dev elopement Kits.

It is not.

Well. Thank you for your reply.
I will try to read the dongle's pcb file and then debug it using j-link.
