This is the first time I deal with GPS module. I’m becoming mad with such a simple thing … I cannot get any informations out. I’m probably doing something silly because I’m not used to .
After 5 minutes under the satellite. Nothing on UART2 RX from the GPS module

#include <TinyGPS++.h>

TinyGPSPlus gps;
HardwareSerial Serial1(1);

void setup()
{

// Setup GPS ON PIN 21
pinMode(21, OUTPUT); // sets the digital pin 13 as output
digitalWrite(21, HIGH);
delay(1000);

Serial.begin(115200);
Serial1.begin(9600, SERIAL_8N1, 17, 16);
}

void loop()
{
Serial.print("Latitude : ");
Serial.println(gps.location.lat(), 5);
Serial.print("Longitude : ");
Serial.println(gps.location.lng(), 4);
Serial.print(“Satellites: “);
Serial.println(gps.satellites.value());

Serial.print(gps.time.minute());

smartDelay(1000);

if (millis() > 5000 && gps.charsProcessed() < 10)
Serial.println(F(“No GPS data received: check wiring”));
}

gps.encode(Serial1.read());

I also had much trouble.

One issue was I wired the GPS to normal serial when it only worked reliably using 3.3v TTL… I was getting bad sentences, so my lora decode was presenting gibberish. I bashed away for days before I gave up and tried to just display the raw feed from the GPS, and realized it was bad. I used a TTL 3.3v usb adaptor to connect directly to the GPS, and saw that it was good, it was just how I had it connected - .

I was using a Wemos D1 Mini (ESP 8266) like you.

My suggestion is bypass the Arduino, until you get data from the GPS directly to Putty on PC using USB TTL. If your GPS won’t send data to a PC, it’s not going to work with the Arduino…

Try something like this. https://core-electronics.com.au/usb-to-ttl-serial-uart-rs232-adaptor-pl2303hx.html

I’ve spent ages on GPS nmea feeds at 4200 (standard speed), I might be able to help more.

Hi ccadic! This is a very nice project, and I’m really impressed with the hardware that you managed to put together!
I’m curious about what you’ve managed to accomplish on the protocol side? Is there any code, or even some sort of template/outline that you’ve been working on regarding how the network would operate?
It would be interesting to have something that works on your platform, but would also would also work on an off-the-shelf esp32-lora-oled module tied to a phone via bluetooth.

Tnx for the Kong’Grats
I’m presently coding (arduino IDE) the main functions of the board. A lot of code is not yet written( I’m not too good at coding in arduino IDE)
I planed to use a MESH protocole

pls FORMAT your code
to avoid very long code and txt

example:

This text will be hidden,
until clicked

…which will get you:

ccadic · June 19, 2018, 3:35pm

Yes. I will. When finished. I prefer focusing on the code to work rather than cosmetic presentation

BoRRoZ · June 19, 2018, 3:36pm

ok… have it your way, irritating long post deleted

kersing · June 19, 2018, 5:47pm

This is not about formatting your code in the programming environment, it is about formatting your message on the forum. As courtesy for the forum users you should insert two lines to format your message. Or is that too much to ask?
Just insert [code] before you code and [/code] after.

kersing · June 19, 2018, 5:51pm

As the code is interesting I reformatted and restored it.

ccadic · June 28, 2018, 10:21pm
