Dialog Smartbond Bluetooth Low Energy – Software

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.

1. Is this feature supported by SDK?
2. If yes, how to enable it?

Kind regards,
Raz

Hi support team,

I am trying to dig into the DSPS example based on the SDK5.0. I have question regarding the security.
I ran across CFG_APP_SECURITY so I tried to set up device side according to the this tutorial.
http://support.dialog-semiconductor.com/resource/tutorial-6-pairing-bond...

When i try to connect from android app, I am requested to fill in pairing key and then connection is working.
Now I would expect host side to be not working, but when I load host app into the another DA14580 chip, connection is estabilished and data are transferred.

My question is, have I missed something, is the security really implemented by having done those steps marked in the tutorial? Is the connection secure in some way now?
