What is Simple Secure Pairing (SSP)?

Simple secure pairing (SSP) was introduced with BT2.1 to increase the security provided by a Bluetooth link as well as make the pairing process more user friendly. Many of the changes relate to how a user interacts with devices during the pairing process which may not be suitable for those applications that do not have user interaction such as M2M applications. For this reason Laird Technologies can also supply BT2.0 modules as well that use the legacy pairing most people are familiar with.
