nRF Connect & VS Code Extension Display CONNECTED DEVICE as UNKNOWN

[Himansu]

Hi,

I am using VS Code with nRF Connect Extension and facing a device detection issue. This is working fine but starts an issue after updating the latest nRF Connect Extention before three days. I follow below step but my issue is not resolved:

 (+) vscode nrf Connect no devices found - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

Due to this problem, I am not able to do flash or reset the board or recover the board.

I have updated the latest nRF Command line tool and nRF Connect SDK and Programmer.

Hardware: (Both Hardware Display UNKNOWN Connect Device)

1. nRF52840-DK

2. J-Link EDU Mini + RAK4630 Core Board

Programmer: 3.0.8 Log (Same Message Display for Both Hardware)

Hi Edvin,

Can you try to make sure the DK is plugged in and powered on (so that LED5 is on/blinking), and measure the voltage on VDD? What is it?

Ans: LED5 Blinking

Voltage: 3.0V

Does the DK work if you plug it into another computer?

Ans: Sorry, Only One computer is Available..

What if you are trying to use nRF Command line tools directly from a cmd window?

Thanks, After running above command my VS code also able to detect nRF52840 SoC and I am able to flash board using both J-Link EDU and nRF52840-DK.

Thanks,

Himansu Donga

Hi,

Maybe it's not directly your problem but I am using nrf52DK (nrf52832) and latest version of nRF Connect for VS Code v2023.4.179 has some bug. After when I downgrade version this extention my development board worked today.

regards
