nRF Connect not able to open COM

[Timur Beganovic]

nRF Connect suddenly can not find the COM port to my nRF Dongle. The same setup used to work fine untill today. I reinstalled the nRF Connect, JLink drivers but it is still the same. As you can see, the device is listed in the Device manager.  I searched about this problem but couldn't find any solution. Please help!

The error was eliminated after I updated Windows. Unfortunately, I can not tell what caused the error but it is obvious that it has nothing to do with nRF tools or JLink drivers.

Hi,

I have the same problem as you.

I use PCA10000 dongle (nRF51). After "Erase all" it was automatically programmed.

This is weird because communication with the dongle is OK, nRF Connect was able to read the serial number and processor type. Why later write that it is not possible to find COM7 interface? In my opinion, this is an evident bug in nRF Connect.

... in my case probably the reseon is simply nRF Connect dasn't support my dongle;(

in tutorial to nRF Connect is description:

"Supported devices

• PCA10028 nRF51 Development Kit
• PCA10040 nRF52 Development Kit
• PCA10056 nRF52 Development Kit
• PCA10031 nRF51 Dongle"

Have you ever been able to connect to your dongle through nRF Connect in the past?
