HI: I'am an engineer of BLE. And II want PC&Mobile connect my BLE equipment(51822) by type in password like wifi or most of bluetooth Headset. what should I do. which paragraph of code is most related ? which API I can use? thank you! best regards.

supplement: My platform:SW(Keil4+Nordic SDK 5.1.0+SoftDevice S110 6.0.0).HW(N51822QFAG0).Now I test the SOC with "nrf UART_V2","nrf Toolbox for BLE".I want to connect my BLE device with passkey,but I don't know what to do?

If you don't have a display or any interface that supports input of a passkey, you need to use static passkey. Please see this question.

This example on GitHub may also be of help.

If you don't set any characteristic to require encryption but set them to open BLE_GAP_CONN_SEC_MODE_SET_OPEN() then no bond will be required. And you will be able to connect and do everything without bonding. You can try to set the permission of a characteristic using BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM() then encryption will be triggered automatically.

Note that bonding process only required once. After that no passkey entering required.
