I have been able to parse nmea sentences using a TinyGPS+ port ( very similar to TinyGPS – same author) by using bufferedSerial to buffer the NMEA strings so that TinyGPS can parse them in the main loop

I have these imports :

#include "TinyGPSplus.h" // can also use TinyGPS
#include "BufferedSerial.h"

then I create these :

TinyGPSPlus gps;
BufferedSerial uartGPS(XBEE_DOUT, XBEE_DIN,1024); // tx, rx,buffer size //

in main ( before the usual “while(1)” loop: ( “Setup()” in ArduinoLand
I set up the baudrate of the GPS interface :

// set up UART to recieve GPS strings
    logInfo("setting up GPS serial port");
    uartGPS.baud(9600);

and then in the While(1) loop ( or if you are From ArduinoLand (loop() )

// parse all the data in the serial buffer
        while(uartGPS.readable()>0) {
           // gps << uartGPS.getc();
            gps.encode((char)uartGPS.getc());
        }

you can then read the GPS parameters off exacly like the TinyGPS / TinyGPS+ libraries show , ie.
int altitudeGps = gps.altitude.meters();

node-red is able to get the LoRa message payload and send it via a POST method ( using the AEP model ).

you are also able to process the data inside nodered.
