[JohnCC]

Hi,

      I development a elock device to use nordic 52832 chip. I want to transfer some information between phone app and my device. Like UUID / user account / user password.

for against BLE sniffer, we need use AES method to protect our information.

Can I follow  \examples\crypto\nrf_cc310\aes example to do it? Or any suggest for us? Our data transfer flow as below

 - phone app sent unlock command to our device

 - our device sent a random number to phone app

 - phone app response

- our device check response to unlock

Thank you.

John.
