To make your device initiate bonding, you can for example set up your device to initiate bonding immediately after a connection has been established, upon the event BLE_GAP_EVT_CONNECTED. For how to initiate bonding from the peripheral, I would recommend you to take a look at this message sequence chart.

The example ble_app_gls in the SDK does for instance use peer manager to handle bonding.

This video tutorial, part 2 (code walkthrough), gives you an introduction to peer manager.

Thank You for reply. I will use peer manager as You recommend. But I don't understand how it should work. It has to work both with smartphone and NRF51 module. And how can I initiate pairing and bonding on NRF51 device which doesn't have any buttons. Maybe could You tell me more about Peer Manager.

The device manager is our legacy module for handling bonding of devices. Instead, I would recommend you to use the "Peer Manager" module, how to use it is described on infocenter.nordicsemi.com.

I've found this tutorial: devzone.nordicsemi.com/.../ It describes how to use device manager to pair and bond two devices. If I will use it it will implement IRK too for Android BLE? And do I have to implement it in base station and in the transceiver(nrf51822 version) too?
