Hi

Before flashing an example, you need to erase the chip. Use nRFgo studio to erase the chip, by pressing "Erase all" button. You can now flash directly a peripheral example, and it should work out of the box. When using an example with a softdevice, you need to first flash the softdevice to the chip, then you flash the application.

The method of flashing an example without a softedevice is here.
