+ * nRF52840_NB-IoT
+ * Created by Manuel Montenegro, Feb 05, 2019.
+ * Developed for MOTAM project.
+ *
+ *  This application stablish a bypass connection between USB UART and Arduino serial 
+ *  pins UART, i.e. D0 and D1 pins.
+ *
+ *  This is used in order to manage NB-IoT module directly through AT commands.
+ *
+ *  This code has been developed for Nordic Semiconductor nRF52840 DK and NB-IoT Arduino
+ *  shield. Tested NB-IoT shileds: AVNET BG96 and Sodaq Sara N211.
