Rob Meades / C027_Support_N

Support for LISA-N101

Fork of C027_Support by u-blox

This is a variant of the C027 driver code for the C027N version, i.e. the one with the Neul/Huawei/u-blox Cellular Internet of Things module on board. The AT command interface for this module is entirely different to the AT interface for the other u-blox modules, hence this fork of the driver. Work is underway to rearchitect the original C027 driver so that a merge can be done.
