How to ensure secure ble connection?

[SaiTeja]

Hello, 

For ble communication in an application, I am usnig NRF52832 based boards. I am using ble_app_uart example for peripheral and ble_app_uart_c example for client. I can also connect to my peripheral using nrfconnect mobile app. 

Is there any way to make the peripheral device to connect to it's corresponding central device only ?  I don't want to connect my peripheral device to mobile phone even if user wants to do it. It should get connected to it's corresponding central device. 

I wanted to do this to ensure full control over peripheral device. If there are other ways to ensure this, please let me know.

Please guide me the process to achieve my requirement.

Regards,

Sai Teja.
