Best solution for small area demos

Hello everyone,
I have to show a create a demo showing the functionality of the contextual marketing using beacons.
The app will run in quite small offices since it is a commercial demonstration. I have made some tries and I was wondering which SDK is more suitable for my purpose.

I would like to get background notifications and the quickest response possible from my app walking in the room.

Thanks in advance,

I’d probably suggest taking a look at our app templates:

It’s the quickest way to get started, and you can take them and modify them any way you like.
