Re: [ecs] a more general bluetooth question (clarification) Mark Gilmore Sat, 15 Apr 2006 07:39:49 -0400

this is the goal and possible solutions that i envision:

goal:
to know when *any desired* BT device is within the area (for 
proximity detection)


possible solutions (best to worst):
1) OS system calls (or a sys utility) could periodically discover all 
active BT devices
I'm looking into this now:

2) Commercial utility pgm could do same as above (some cost to customer)

3) Adapter/software combo would do same (more cost to customer)
