Multiple issues date=August 2012 A Bluetooth stack is software that refers to an implementation of the Bluetooth protocol stack. Bluetooth stacks can be roughly divided into two distinct categories: # General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers. Support for additional Bluetooth profiles can typically be added through drivers. # Embedded system implementations intended for use in devices where resources are limited and demands are lower, such as Bluetooth peripheral devices.
