how I can to activate the password on nRF51822 for connect to BLE?
Do you mean passkey? Could you be a bit more specific regarding your setup? What are you running on the nRF51822? S110? What are you connecting it to? A smart phone? PC? Have you connected anything to the nRF51822 so you can input or display a passkey?
