/* 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/U260/U270 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-G35, C027-U20, C027-C20 (for shield set define C027_FORCE_SHIELD)
   - NXP:       LPC1549v2, LPC4088qsb
   - Freescale: FRDM-KL05Z, FRDM-KL25Z, FRDM-KL46Z, FRDM-K64F
   - STM:       NUCLEO-F401RE, NUCLEO-F030R8
                mount resistors SB13/14 1k, SB62/63 0R
