Now, I want to add passkey to my device but it dont have display/ keyboard , only one power button. I got to know about pairing generation key methods which are: Justworks(unauthenticateden-USTelligent Community 13Thu, 28 Jun 2018 09:48:31 GMThttps://devzone.nordicsemi.com/thread/138064?ContentTypeID=1Thu, 28 Jun 2018 09:48:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29b3c594-42ad-4d02-98a2-85b0545167d9run_ar<p>Not sure what application you have and what level of security is required. But I guess it would be easiest to use application layer encryption to exchange the passkey. Just make sure you add a counter to something to the passkey to avoid replay attacks. Maybe also consider using just works in addition.</p><div style="clear:both;"></div>
