decoupling capacitor

[GANESHA]

why we are using a decoupling capacitor and how we can decide what value to choose for it?

Hello, 

To learn about decoupling capacitors, I suggest looking at this tutorial and this one. For values regarding decoupling of any nRF device, please see our reference circuitry and use those values given there.

Kind regards,
