livoxProto1: Connecting to bcast-advertised device works :)

We tested it.
It's important to note that between test runs, we need to take
into account the fact that the Avia stops sending bcast adverts
when it's been handshaken.

So the retry-delay-ms may be longer due to the fact that the Avia
may not be sending adverts for a good portion of that retry-delay-ms
time.
