Problem with BLE read data

[homzik]

Hello ! I'm beginning work with BLE . I have a project in which nrf51 is a central. App from smartphone will sending to central any key for example "3214941E0" when central accept this key for example led light up. I already read all tutorials but I still don't know how i should do this.

I want any link with tutorials how i can do this or any suggestion.

Project will be somethink like "Smart gate" . When key is ok app will send signal to open gate .

I'm afraid these Tutorials and nRF5 Get Started on Infocenter are the best sources, there is no magic bypass from "I don't know" to "my project magically works, I'm done"...

As endnode says, please look at the tutorials section. The central tutorial should answer your question. Maybe you can take another look at that, and see if you have a more specific questions. Note that on the peripheral there will be an write event when the "key" is received so you can choose to do some action based on that.
