Are BLE advertising tokens device or model specific?

The readme contains a list of BLE advertising tokens contributed by community members, in the hopes these tokens can be used by others, so they don't have to sniff their own token. However, I can't find any evidence of anyone successfully using these shared tokens on their beamer.

There's also reports of different tokens for the same model (which would go against the idea the token is shared between models). It's looking more likely to me the tokens are device specific, but I don't think this is enough evidence to say for certain.

Critically, we need to test newly found tokens on other devices - that should give us a better idea.
