- | A number of internet resources helped me. The biggest help came as form of a personal mail from "Ryan", whom I got acquainted with by [[https://www.arduinolibraries.info/authors/cujomalainey|Curtis Malainey]]. It was "Ryan", who first managed the S340 SoftDevice to work with his Feather and he kindly shared his steps with me. This guide is based primarily on his work. | + | A number of internet resources helped me.
