How i can restrict nrf52832 connecttion with the custom mobile application only?

[Heena]

Hello, 

I am working on nRF52832 having SDK 15.3.0, Windows 10 and Segger Studio IDE.

My query is, i want to restrict my nRF board connection to a particular custom application developed by us.

It should get connect to other application like nRF Connect,but within 30 seconds it should get disconnect.

Is it possible?

If yes, kindly guide me, how can i implement it?

Hi,

You could use sd_ble_gap_addr_get() to get the peer address of the connected device and compare it with the address that you want to connect to. If it doesn't match the specific address you could then proceed to disconnect. Another alternative would be to use whitelist, but this would prevent the device from connecting in the first place.

Assuming that the Central has a fixed address ?

If the Central is a phone, that is normally not the case.

Sure it is - just like a website that will only let you in if it "knows" you!

You would need to have some sort of secure authentication/authorisation process ...

Thanks for the reply.....

When we say authorization /authentication process, we can create custom service and expect user  to respond back with particular password after connecting  or something like this?
