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!

    Hi,

    Seems weird, and you haven't changed anything since last time you tried?

    Can you try upgrade the JLink firmware? Also try a different COM port.

    Hi,

    thank you for the response.

    I uninstalled and installed again nrf Command Line Tools as well as nRF Connect. It didn't help. I also tried different COM ports without success.

    Which JLink firmware version do you recommend?
