What code can print the data in the GPS Module? , I'm using GY-NEO6MV2.

biancadelos · November 8, 2018, 4:23pm

I found this code (see attached file) online,
but I am not sure if it will print the data.

Also, I am confused on it's wiring because I already had a ESP8266 I think that I should connect it there?

Please help thank you

I'd much rather you posted it.

What happens when you try it ?

AWOL can't you see the file?

No. I'm posting from my phone.

AWOL here's the code:

/*
PPS->free
rxd->11
txd->10
gnd->gnd
vcc->5v
*/

#include "SoftwareSerial.h"
SoftwareSerial gps(10,11);
void setup(){
Serial.begin(9600);
gps.begin(9600);
}

void loop(){
while (gps.available())
Serial.write(gps.read());
}

Where are the code tags?

What IS the problem? The code expects the GPS to be connected to pins 10 and 11, and will write (should be print, since GPSs only send ASCII data) what it reads from those pins to pins 0 and 1.

Suppose that the distance measured is 34. What are you going to output? It makes no sense to have separate output statements for every discrete value. An output statement for a range of values does make sense.

For a cheap temperature/humidity sensor, it makes NO sense to output the values to 2 decimal places. If you get 1/2 degree or % resolution, you are doing good.

void loop()
{
 
  delay(2000);  // Delay so DHT-11 sensor can stabalize

Psst. That's just plain stupid. Even if you COULD use two instances of SoftwareSerial to listen to two devices at the same time (you can't), you would read NOTHING from the GPS for more than two seconds, while it continues to try to write data to the Arduino. Most of it's data is going to end up on the floor.

    long int time = millis();

RTFM. What kind of value does millis() return? It is NOT a signed value.

    while( (time+timeout) > millis())
    {
      while(esp8266.available())
      {
        char c = esp8266.read();
        response+=c;
      } 
    }

Great. A delay with lipstick. It is STILL blocking code.

long duration,distance;
duration= pulseIn(ECHO_PIN,HIGH);

More blocking code.

I guess you are in no hurry to get this project working.
