I recently purchased an SparkFun Triband GNSS RTK Breakout - UM980 for my project.  
I am using the library : [GitHub - sparkfun/SparkFun\_Unicore\_GNSS\_Arduino\_Library: An Arduino library for the UM980 and other Unicore based triband GNSS RTK receivers.](https://github.com/sparkfun/SparkFun_Unicore_GNSS_Arduino_Library)

Regardless of whichever board I select I am facing this error. Pls support.

I am able to see data on the UPrecise app.

You need to install the Sparkfun extensible message parser library.
