If you can find any links on this I would be interested... I have
used various OBEX object tools like ussp-push to determine location
(indoor) with BT but most of those solutions are very noisy so you
have to overprovision your solution substantially... and of course,
it is driver dependent, so you have to calibrate for your particular chipset...
Lots of good boilerplate code in Larry Rudolph's book if you have a
free couple dozen hours a week to dive in...

CSR, who make most of the chipsets for cellphones in the world is
doubling down on BT... couple good articles on their future offerings at

I see you can get Bluetooth transceivers for almost nothing:

($2 w/shipping; I think Micro Center also sells them for $2.)
And I've heard about projects where the audio "profile" for Bluetooth is
abused to allow the exchange of some coarse data without requiring any
drivers.
I'm wondering if Bluetooth might be a really cheap way to add wireless
networking with a 20m range to any embedded project with a USB port, and
also not necessitate an IP stack.
Anyone run across projects where Bluetooth is used in this fashion?
