This may be a naive question, but I have an idea for a Bluetooth application, and need some help in either sourcing or building the units.
What I need is 2 devices - a 'Host', and a Remote unit - as small as possible - that connect to each other over bluetooth.
All they need to do is 'know' that the other is there - within a given range (5 mtrs). If the remote moves out of this range - or disappears then the Host needs to give out an Audible signal.
Easy !!
Is there such a thing available ?
Could this be built easily from Off the Shelf components ? (I am a Windows application programmer so could probably do the programming).
Any help appreciated.
