#73428 The lack of TX is unfortunate, but increasing size of RX FIFO makes it manageable, especially if you are using HW serial. Of course, if you can get a GPIO pin connected to the RX on the GPS, you can use SW Serial to send commands to GPS.

If you are only interested in GPVTG, I suggest using NeoGPS, as it offers precise control over which sentences it ignores. You won’t need to do any buffering and parsing.

Note, TinyGPS ignores GPVTG, gets speed from GPRMC.
