DSPS DA14580 security

Hi,

Our device is a source of information that we want to share with the user in our mobile application, however we would like to own the information and not let 3rd party write another mobile app and get the device information. For this purpose Bluetooth define a "Secure" challenge-response authentication: Both sides need to know some secret string and only if both are satisfied that the other side "know" the secret a connection will be permitted.

We use SPS profile to transmit the information to our mobile app.
