How Go-tcha Pokemon Go products get away with not being blocked.

So it seems that the Organizationally Unique Identifier (OUI) part of the MAC address of the bluetooth device is using Nintendo’s assigned address space to get around being blocked on MAC.

This is the initial part of the MAC 7C:BB:8A on the Go-tcha I have. Pop that into https://www.wireshark.org/tools/oui-lookup.html and you’ll see: 7C:BB:8A Nintendo Nintendo Co., Ltd. as the result. I suspect they might have gone even further to try and not get them blocked and tried to narrow down allocated address space in the rest of the MAC address for the Pokemon Go accessories range. It’d be a decent way to circumvent Nintendo blocking as this method could affect genuine product purchases.
