My phone, laptop, or watch can't be tracked by their Bluetooth transmissions. For a start I don't own a watch that has Bluetooth, but also my phone never has Bluetooth turned on except briefly when needed, which would be about twice a year, and my laptop never has Bluetooth turned on. As for Apple products refusing to turn Bluetooth off, that would be one of the many reasons I don't buy their overpriced tatt.
You might be able to track me via my wireless headphones but only if you're very close nearby and all you're going to learn is how frequently I make tea / coffee. Hourly as it happens.
