I need something that is going to search out active bluetooth devices and attempts to send items to active devices (eg. mobile phones) within proximity to this transmitter.
It needs at least a 10-15 metre range and it needs to be able to easily updatable as the content I will be sending will be changing frequently.
I'll be using it at an event on a beach, and it will be able to rigged to any power source so that is no big deal, but I would prefer for it not be over $1000.
If you could tell me where I could get one as well, that would be tops.
