No internet connectivity = crash

Hi There,

Trying to use the Indoor location example.

It is quite common that large venues not to have an internet connectivity. Indeed where I live it can be tough to get a 2G signal!
In the past you could add beacons by Mac address but this has been deprecated. When calling addBeaconWithIdentifier with no internet connectivity you get a crash.

How long can I keep using Mac addresses?

Thanks,

Al
