/* 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 remove define C027_USEONBOARD)
+ - 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
