libloragw/src/loragw_gps.c:
832        if (nb_fields != 13) {
#
Change that to:
832        if ( (nb_fields != 13) && (nb_fields != 14) ) {
# This change will accept NMEA G?RMC messages with 13 or 14 fields, not only those with 13 as before. The L76K receiver apparently defaults to sending 14-field-messages.
