Where there is a BLE pairing routines

[chad.ou]

NRF52 on-site training for today, know BLE pairing use OOB way will be a little bit more simple and safe, and then want to ask next, on NRF51822 platform have the corresponding related routines can refer to.

The nRF51 SoftDevices support the OOB pairing method, but it does not have any NFC peripheral.

So you would need some other transport to share the temporary key between the devices.
