@twyatt Hi. Can u add an iOS Filter by mac address from advertisement data?

[twyatt]

Unfortunately (as far as I'm aware), Core Bluetooth (iOS) does not expose the MAC address, making it impossible to filter by that on iOS.

Let me know if you happen to find a Core Bluetooth API that exposes MAC address.
