Chapter 6. The Serial Port Profile

Introduction

All of the profiles listed in Table 6-1 are based upon the The Serial Port Profile. Potentially it will impact upon new profile development; in one way or another, you will find yourself returning to it on a regular basis.

With its firm foundation in all the profiles illustrated in Table 6-1, it is clear that a sound knowledge of the Serial Port Profile is one of the key prerequisites of current profile development. Its purpose is to provide a set of protocols and procedures which in turn, allows RFCOMM to provide serial port emulation for Bluetooth-enabled devices. The scenario provided for this profile, as shown in Figure 6-1, illustrates two devices communicating over an emulated serial communications ...
