BLE Scan with random mac devices

[kleber.martir]

Hey guys

I'm creating a project similar to what's already out there in the community, but I'm facing a big problem. The project is to identify BLE devices and post them on the MQTT server, however I bought 3 smartcards (like badges) but these have a random MAC, that is, they change with some frequency, so I can't identify who is who (each badge will be from a employee). What can I use to identify each badge?

Can someone help me? Thanks

Please check the user manual of the BLE devices. There may be a way to assign a static MAC address.
