Want to advetise nrf51822 for limited time

[swap007]

Hello i am new to nordic BLE chip. I want to put security feature. i.e. when i press push button by thisGPIO library. BLE should be visible only for that time frame, can be connect with central device with android/ios app. When i release button it will remain connected to the same device but not available for connection with other masters.

Thank you in advance

Once peripheral device is in connection with central device, it stops advertising so there is no chance that it is visible to other central devices.

Pressing push button to enable/disable advertisements is achievable and easy task suing start/stop advertising APIs.
