u-blox / ublox-cellular-driver-gen

This class provides SMS, USSD and modem file system support for u-blox modules on the C027 and C030 boards (excepting the C030 N2xx flavour) from mbed 5.5 onwards.

Revision:
5:b935404dcf7c
Parent:
4:4f2c12992e17
Child:
7:a9eea2dbdd68
Tests now pass on C027: cope with filenames being returned without quotation marks, reduce file size to write since some modules can't keep up when there's no HW flow control, increase USSD timeout, simplify JSON template and run test without debug.
