At least over here all cats have an RFID implant injected after their first vet visit. I'd try to work with that instead of putting a BLE on the cat. Your localization target ("Cat is in kitchen" etc.) is coarse grained enough to make it work with RBP's.
- bo0tzz 6y agoAs far as I know, the usual range on those implants is no more than ~30 cm, so I expect you might need a pretty powerful transmitter to find them across a room.
- rtkwe 6y agoThat's less a hard number and more a limit of how much power you're directing at it (with limits due to the inefficiency of RF energy transmission mostly) and how sensitive your receiver is. The passport RFID tags have been read from over 200 feet away for example.
