I have a bluetooth beacon device that advertises a name depending on
its configuration (connectable or not).
Sadly, in Bluez, the first time it sees it while advertising its name,
it caches it which is nice for future discovery.
Except it doesn't because I don't want to see this name while it
advertises in non-connectable state as it is "not" the same device
anymore (sort of).
I guess what I'm asking is if we can make Device name aware of the
connectable state and only use it if it matches state when it was
cached.
See some btmon trace of what it looks like in both configurations:
