u-blox / Mbed OS example-ublox-uart-power-saving

Example program for UART power saving configuration of cellular modem. This program can be used with UBLOX_C030_R412M board. It has nothing to do with 3GPP power saving mode.

Dependencies:   ublox-at-cellular-interface ublox-cellular-base ublox-cellular-base-n2xx ublox-at-cellular-interface-n2xx
