let's try to get the GPS working first by testing this code, I haven't tested it though
#include <TinyGPS++.h>
#define neo Serial
TinyGPSPlus gps;
String lati = " ";
String longi = " ";
void setup() {
neo.begin(9600);
}
void loop() {
if (neo.available()) {
while (neo.available() > 0) {
gps.encode(neo.read());
if (gps.location.isUpdated()) {
lati = String(gps.location.lat(), 8);
longi = String(gps.location.lng(), 6);
}
}
}
static uint32_t prev = 0;
if ( millis() - prev >= 500 ) {
prev = millis();
Serial.println("lati: "+lati);
Serial.println("longi: "+longi);
}
}
lati and longi are in the serial monitor but no coordinates. Just to verify that the GPS is working, I uploaded the old code and tested it and it worked that way. But then it only sends to me. So should I have the GPS modules TX and RX pins plugged into the Arduino Nano's RX and TX pins?
@KASSIMSAMJI YOU GOT IT WORKING!!! Thanks a bunch! I moved the GPS module closer to a window and BAM! It worked. Thank you and everyone else who helped me with this issue. I marked the solution box up in the prior code you sent. Thank you again.
Just in case anyone is interested, here is the final code. I had to put all the GSM Listening functions back in, as well as move the pins from the RX and TX back to pins 8 & 9 on the Arduino. But the way @KASSIMSAMJI and @mfusco setup the code was perfect. Thanks again to everyone, and enjoy this project.
