how to make nrf51822 central to transmit the status of a pin ?

[Muphy]

I have: nrf51822 bluetooth module, STlink V2, Keil, segger studio, nrf51 sdk and softdevice files.

I have achieved making the led blink at a ble peripheral device by nordic connect app via this link https://www.youtube.com/watch?v=_-d2d6Vc3lg&list=WL&index=96.

I want to make a ble master from which I can connect to the peripheral  and send the status of a button to the peripheral. (Its like when I poweron, the master search for the peripheral and connects to it and send the status of one of its pin).

Can you please guide me how to do that.
