/* This example was tested on C027-U20 and C027-G35 with the on board modem. 
   
   Additionally it was tested with a shield where the SARA-G350 RX/TX/PWRON 
   is connected to D0/D1/D4 and the GPS SCL/SDA is connected D15/D15. In this 
   configuration the following platforms were tested (it is likely that others 
   will work as well)
   - U-BLOX:    C027-XX.
   - NXP:       LPC1549v2 
   - Freescale: FRDM-KL25Z, FRDM-KL46Z
   - STM:       NUCLEO-F401RE, NUCLEO-F030R8
