GPS Module don't provide full data

Question

I connected my gps module (NEO-6M) with esp32doit-devkit-v1 board. The module provided data but many data are missing.

My pin configuration:

GPS ------- ESP32
VCC ------- 3v3
GND ------- GND
TX -------- RX2 (pin 16)
RX -------- TX2 (pin 17)

Baud Rate: 9600

My code:

#include <Arduino.h>
#include <TinyGPS++.h>
#define TXD2 17
#define RXD2 16
TinyGPSPlus gps;
void setup()
{
 Serial.begin(115200);
 Serial2.begin(9600, SERIAL_8N1, RXD2, TXD2);
 Serial.println("Started......");
}
void loop()
{
 while (Serial2.available())
 {
 Serial.write(Serial2.read());
 // gps.encode(Serial2.read());
 // if (gps.location.isValid())
 // {
 // Serial.print("Latitude= ");
 // Serial.print(gps.location.lat(), 6);
 // Serial.print(" Longitude= ");
 // Serial.println(gps.location.lng(), 6);
 // }
 }
}

OUTPUT

my output

• Majenko: The output looks perfectly fine. You just don't have a GPS signal.
• Vaibhav: @Majenko is right put your GPS outside (in open sky) then you will the latitude and longitude with other parameters as well.

Answer 1

GPS seems to be working and informing you that you have no signal. Usually happens inside buildings, when far from a window or when antenna isnt properly connected.

Testing out of doors is many times not possible, so try placing your antenna next to a window with a partial view of the sky. Wait for a couple of minutes until you get a fix on 4 or 5 satellites.

• Rob: have also found this happens when the power to the module is lower than needed, for example 5v being shared with other modules such as a 1602 display
