Listen for data changes in already detected beacons

[hughbris]

The current API (evothings.eddystone.startScan) listens for new beacons and exposes their data.

My use case (which I think this is common if not normal) is to listen for changes in the data broadcast by beacons once I have found them. Specifically the 'url' field in my case.

Without continually running a loop scanning, checking values, then stopping, I can't see a way to do this using the plugin. I am pretty sure the loop approach is going to miss some changes to values, and I'd expect it to crash eventually.

The sort of interface that I would like to see is in the eddystone-beacon-scanner node module. There you have events for 'found', 'updated', and 'lost', as well as a flag on the scan method to report duplicates. The 'updated' event would nicely address the use case I'm describing above. Unfortunately, I don't have enough JS packaging-foo to port this to a Cordova plugin (happy to be advised on that!).

So I guess this is a feature request. Would you consider extending the interface to this plugin to listen for changes to the data advertised by the beacon once it has been found? That would make it much more useful.

Oh, I've raised this in gitter, but been told you are all busy restructuring the company, so I expect it will get buried by the time you are all back on board. Thanks!
