How to avoid the other android app connect to my nordic board?

[ligang]

When I test the example, When I disconnect my phone of the nordic board. I can use the other Phone to connect the nordic board

So, I think that how to avoid the connect.

When I use Huawei watch, the connect need me to touch the watch.

But, the nordic board , I can not find this function.

I wish somebody can help me , give an example to solve the question.

Thanks!

As a peripheral the only way to avoid a connect is to have a whitelist with the devices you want to accept connection requests from. You can however disconnect immidiately (if a button hasn't been pushed for example, or only allow bonding if a button has been pushed.
