Hello, It doesn't seem possible to mimic a IEEE public BLE MAC address using the BLE stack provided by Noridc. But how easy is it for others to roll their own BLE stack that does allow them to mimic MAC addresses that's been assigned to other modules? Are there publicly available BLE stacks that run on common BLE chips that allow arbitrary MAC address assignment? I'm not trying to do anything nefarious, but I was asked if replay attacks for beacon data is a common enough problem.
