What kind of "broadcast" ?

Note that the nRF51 products are not recommended for new BLE designs:

Thank you for your response. By broadcast I mean all masters device can receive packages of data. I want to modify my previouse android app to showing data from sensor on the screen. The problem is that I cannot find example how to do this, especially with using gpio.

So you will have to put that data into the Advertising packets.

So start with the Advertising Tutorial:

Here's a couple of threads about having "dynamic" advertising data:

Which is what a Beacon does - so you could also look at the Beacon examples ...
