Security Mode

Bluetooth has three defined security modes, these are: Security Mode 1 – this is a non-secure mode, since the device will not initiate any security; Security Mode 2 – this provides a service level enforced security mode, providing a flexible access security method by allowing multiple applications to use different security requirements in parallel; Security Mode 3 – this is a link level enforced security mode. The Bluetooth device will initiate security procedures before the link is set-up.
