I'm trying to understand the basic behind a GPS NMEA sentence. I saw one datasheet for further reading https://www.sparkfun.com/datasheets/GPS/Modules/LS20030~3_datasheet_v1.0.pdf
GPS send NMEA sentence's or data to microcontroller and microcontroller receive data and decode the relevant NMEA sentence
I don't understand what is meaning of this
When we connect GPS receiver to microcontroller then GPS receiver can send data to uart. Data can be send serially to microcontroller. How does microcontroller identify and decode data ?
