Hello,
I'm trying to setup an automated pairing for two devices. My peripheral device is advertising and should only allow connection requests from a specific central device. I've read that using directed advertising will not show my peripheral device on unauthorized devices if they are complaint to the specification. However, a malicious device which doesn't ignore those advertising packets would still be able establish a connection if I'm not mistaken and I would need a whitelist instead. Is it possible to add a specific device (I know the device address, it's randomly generated but doesn't change) without the IRK such that only this specific central device is able to establish a connection and perform the automated pairing?
Best regards
Tobias
