I have a very, very simple requirement for a bluetooth module/Arduino solution. I want to periodically scan for and report the device ID for any bluetooth devices present. Actual logic regarding further identification of devices would occur downstream. I believe that even SDP is overkill for this application.
In very simple terms, I want to use this information to inform my home automation solution whether or not certain individuals are home.
I'm quite comfortable with Arduino development and interfacing with hardware; have done extensive work with XBee and other RF devices, but have little practical experience with bluetooth development.
My question is this: is this as trivial an implementation as I'm assuming it will be? Should most bluetooth modules available be capable of supporting this requirement? Does anyone have suggestions regarding a specific module which would be a good fit? I'm looking for the lowest-cost solution possible, as most available bluetooth modules seem to be massive overkill for this problem.
