        ``gps,sleep``

        ","
        Send u-blox specific command to put the GPS in backup mode.
        This turns off all parts of the GPS, except for the last known satellite trajectories.

        Use this to get a faster fix, compared to turning off the power to the GPS.

        In order to send a command to the GPS, the GPS RX pin must be connected.

        ``gps,wake``

        ","
        Send just any character to the GPS to wake it from backup mode (see ``gps,sleep``)

        This is u-blox specific.

        In order to send a command to the GPS, the GPS RX pin must be connected.
