NMEA Phrases

Other Hardware Sensors

Hi,

I am looking for the NMEA Phrases for a metric output.

I understand correctly $PMTK314,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*28 this is for imperial.

Can anyone please assist?

Thank you

The manual I found at Sparkfun says that 314 is used to set the frequency of different data sentences. It has nothing to say in there about setting units.

In an Arduino context, I think the TinyGPS++ library gives you distances in meters by default.

Indeed it is.
I used it only yesterday to setup a library function to only have a GPS output GPGGA and GPRMC sentences.
The OP needs to expalin what they are actually trying to do.
