These other protocols include the Object Exchange Protocol (OBEX), the Point-to-Point Protocol (PPP), the Wireless Application Protocol (WAP), and so on. , legacy) applications to work with the Bluetooth wireless technology and ensure the smooth operation and interoperability of these applications. 4). The specifications are publicly available and permit the development of a large number of new applications that take full advantage of the capabilities of the Bluetooth wireless technology.

A slave device during one communications session could be a master in another and vice versa. 2 The Bluetooth WPAN scatternet A scatternet is a collection of operational Bluetooth piconets overlapping in time and space. A Bluetooth device may participate in several piconets at the same time, thus allowing for the possibility that information could flow beyond the coverage area of the single piconet.
