https://devzone.nordicsemi.com/f/nordic-q-a/43264/authentication-scheme-for-central-and-slave-device-pairs-with-keys-preconfigured-in-factoryWe are working on a product with a pair of Central and Slave BLE devices that will be sold in pairs. The plan is to have the pairs preconfigured in factory so that the Central device can only ever connect to the one & only 1 matching Slave device.
