Matters related to pairing only with specific devices

[cabin]

We are developing Master and Slave devices.
A slave must pair and operate only with its master.
It must not be paired with other masters.
Is there any way?

Thank you

Hi,

Which SDK are you working with? Is it the nRF Connect SDK or the nRF5 SDK?
