Pairing ，binding ，short term and long term secret key

[liuyanfeng]

I'm now using nrf52810 sdk16 for product development, but we need to pair bind. So pair bind, generate short-term and long-term keys where I can find it? How can I generate a short-term key and a long-term secret key from the pairing process between a mobile app and a device, and print them out through RTT?

Hello,

pm_peer_data_bonding_load() can be used to retrieve the long term key (LTK) for bonded peer devices. You can try this out by modyfing any of our exisisting examples that includes the Peer manager module. The short term key is not exposed to the application.
