Can you recommend an application level security protocol to layer on top of BT?

[iswara]

Bluetooth technology itself provides a number of different security methods, such as authentication, authorisation, and encryption. They are sufficient for most Bluetooth applications to protect data transmission against eavesdropping.

However, it is possible to create own, application-level security mechanisms too. Bluetooth specification does not set any restrictions for them.

Please refer to the Bluetooth specification v1.1 Core for further details on security methods.
