How to read a NMEA gps data and prase mannually ?

subhadipghouri

Hey guys, I am working with ESP32 Arduino with a GPS module. I have used the TinyGPS PLUS library to praise NMEA data. But if I want to manually o the job like- String operation by reading the Serial Data, how do I do that?

GPS modules send data by serial communication. I can read the data by a simple Serial Read loop but can't store data the everytime the GPS module send the data.

    I am not sure what you mean when you say "can't store data the everytime the GPS module send the data."

    Can't you just declare a global variable

    String nmeaSentence

    and then, in the loop(),

     

    while (Serial.available())

    nmeaSentence.concat(Serial.Read());

     

    When you receive a CR or LF (0x13 or 0x10) the sentence is complete and you can parse
