When I use nrf connect app it gives me error "Error while setting up the device 000000xxxxxx: No serial port available for device with serial number 000000xxxxxx". What would be the problem with that.

Although I search this problem, I couldn't find any proper solution for this error. I am using J-Link OB Arm.

I am using the latest version of nRF Connect. 

Also, I am using BL651 nRF52810 SoC.

Hi,

When you say " I am using J-Link OB Arm", do you mean the on-bord debugger on our DKs, or a standalone J-Link OB device? If the latter, do you have a link to the device?

The serial number does not look correct for a Segger J-Link device. nRF Connect is communicating with the nRF chip over the Virtual COM port in the J-Link. If your device does not support such functionality, you will not be able to use it with nRF Connect. Note that the nRF Connect applications are primarily targeted for use with our DevKits and Dongles. It may not work out-of-the-box with other devices.

Best regards,
Jørgen
