nrf52840 DK is not Detecting in nrfConnect with PC.

[Soham Mistry]

Hello to all,

I have a problem with nrf52840 DK board, it was not detecting in nrfConnect with PC.

Previously it was working but when I had checked one sensor which is I2C based. Once it appears in port and after some time when I had plugged it in my PC there is no detection of the board in my system. 

Also, LED5 is not blinking and USB cable is also good.

I had tried to connect the board through USB by pressing IF/BOOT but then also it doesn't work.

Please suggest some solution for this.

Thanks in Advance.

Regards

Thanks for your fast response.

It was an accelerometer that is I2C based that I had connected with DK board, after some hardware connection when I plugged again the board is not detecting. And after that, I continuously facing this problem.

My system is Win7 64bit.  

Best Regards

Have you tried power cycling the DK?

As Windows 7 was end of lifed on January 14, 2020, we cannot guarantee that the DK will fully function with the OS.

Does power cycling work for you? Are you able to detect the board after power cycling?

 Have you removed the I2C sensor? How are you connecting the sensor? Can you please provide a picture of your setup?

No, Power cycling doesn't work for me.

Also, the connection of a sensor was in the previous week.

Right now, my DK has no connection with any sensor, I am just trying to detect it in my system.

Thanks
