TinyGPS++ does not 'output' NMEA sentences, it reads them and parses the latitude, longitude, altidude etc. Input data files can contain either sentences having all the same talker+sentence_type, like that of test_data/test_data_0_GLGSV. My option now is reconstruct the sentence from its parts and add a recalculated CRC. A value of 0 indicates that the checksum is invalid; however, the fields of NMEA sentence appear in the splitString output if the specified MessageID is matching. Do not reinvent the wheel - NMEA is old, there are millions libraries to parse it. But you only need to get north latitude or west longitude. This program generates well formed sentences with good or bad CRC. , or cycles of sentences like that of test_data/test_data_0_all.
