[quote user="Petar02"]is it possible to bound two devices (two nrf52840 dk boards) with Just Works method pairing and add only those devices to accept list so that only they can connect.[/quote]

Yes, that should be possible.

Thank you, and I have one more question. I have finished bluetooth low energy fundamentals on DevAcademy and Im wondering is it possible to bound two devices (two nrf52840 dk boards) with Just Works method pairing and add only those devices to accept list so that only they can connect.

Yes, you can see how it's done in e.g. the central_uart sample:
