Error while setting up device xxx: Error: No serial port available for device with serial number xxx

[Thomas Nowak]

Hello,

I am currently using the developer board PAN1781 to develop a Bluetooth HID application.
I use the software nRF Connect for  Deskop Bluetooth Low Energy Standalone v4.0.4 for the connection to the developer board PAN1781.

When I select my device I get the following error:

Error while setting up device xxx: Error: No serial port available for device with serial number xxx

Where is the problem? Many thanks for your help

I am not sure if I understand the issue here but just to be sure if we both are on the same page.

1. for the nRF Connect desktop to work it needs to flash a serialized firmware on the nRF chip. And those hex files that we provide are for some specific boards. 
2. It is possible that the board you are using PAN1781 has different mappings of the UART pins to the on board debugger uart handling?
3. The first requirement is that your board should be able to enumerate as a com port so that nRF Connect for desktop is able to initiate some commands to communicate with the board and the chip. But it does not look like your device is being enumerated here? Do you see a com port in your devices list of the  PC?

Thank you for that information. I will check the individual points first.
