whitelist - peripheral

[Miguel]

I need to send data to an APP through NRF52832/840
This data will only be sent when there is a match with my APP. Once I have established 
a first communication with my APP, it already recognizes it when 
there are future pairings. I also need this firmware to be safe when it comes to pairings, 
that is, if by chance a second APP tries to connect it, this 
is not possible because NRF52 will already be configured for the first APP.
 
If there is already a similar example that can help us ?
it will be very useful. I think that is whitelist

Hi, take a look at the HID peripheral examples (keyboard).

Best regards,
