Please help. I can't seem to find what it is that i'm doing wrong. When I run the code it works well for the first 4 uploads until it gets to "if(counter == 5) loop where it stops uploading the data correctly.
I want to upload the lat, lon, signal and batt every 20 seconds and everytime the counter reaches 5, i want bal to be added to the upload.
Here is my code.
#include <TinyGPS++.h>
#include <SoftwareSerial.h>
#include <AltSoftSerial.h>
#include <String.h>
SoftwareSerial mySim(5, 4);
AltSoftSerial neogps;

// put your setup code here, to run once:
Serial.begin(9600); //Begin serial communication with Arduino and Arduino IDE (Serial Monitor)
mySim.begin(9600); //Begin serial communication with Arduino and SIM800L
neogps.begin(9600); //Begin serial communication with Arduino and NEO 6M GPS module
}
void loop() {
// put your main code here, to run repeatedly:
while (Serial.available())
{
mySim.write(Serial.read());//Forward what Serial received to Software Serial Port
}
while(mySim.available())
{
Serial.write(mySim.read());//Forward what Software Serial received to Serial Port
}

}
}
}
