Hi Fares Elec!

You can use one of the examples in one of our SDK's.
The latest supported SDK for the nRF51822 is SDK v12.3.0.
There are precompiles hex-files you can flash to your board that will allow you to connect your smartphone.
Remember that you will not be able to connect to most BLE devices directly from your phone's bluetooth settings. You will most likely need a mobile app to connect to your device.

For example;
You can flash the ble_app_uart example to your device, and use the nRF Toolbox app (available on Android, iOS and Windows phone) to connect to the device.
You can read more on the infocenter-page of the UART-example about how to test it with your device.

Best regards,
Joakim.

So you were able to find the nRF51 with SDK v.9, but not with SDK v.12?
Are you sure that the device is advertising (LED 1 should be blinking)?
Are you using the correct softdevice? SDK v.9 supports softdevice S110, but there is no support for that softdevice in SDK v12. In SDK v12 you should use S130 SoftDevice v2.0.1.
Best regards.
