First of all I recommend to use the nRF52-DK (nRF52832) for new development, the nRF51422 have not been updated for a few years. There are various BLE examples (central and peripheral role) in the nRF5 SDK:

To provide some guidance to your question I would need to know for instance the TI CC256MODA module operating in peripheral role (advertising) or central role (scanning) for peer BLE devices?

Thanks for replying.

TI's  cc256moda bluetooth is working as master and nrf5122 bluetooth is working as peripheral.

You may use the glucose application as a starting point, it will output the passkey:
