Promake GPS L86

Description

The ProMake GPS L86 is a POT (patch antenna on top) GNSS module with 99 acquisition channels and 33 tracking channels. The L86 combines EASY™ (Embedded Assist System for self-generated orbit prediction) with LOCUS™ (internal logger) and AlwaysLocate™ to achieve excellent accuracy with low power consumption.

The ultra-compact design and low power demands, combined with its excellent precision and high sensitivity, makes the module suitable for a broad range of IoT applications such as portable devices, vehicles, asset tracking, security and industrial PDAs.

Software

Developement using Arduino

To set up the hardware, you can easily plug this module into:

Module3 slot of your ProMake® Arduino Nano Kit

or

Module2 slot of your ProMake® Arduino Uno Shield

or

Use your breadboard to connect the Power and UART lines.

To start coding you need to install:

Arduiniana - TinyGPSPlus
"NeoSWSerial" (by SlashDevin)

in your Arduino® IDE. Then use the code below to program the Arduino and open the "Serial Monitor" to see the readings:

#include <TinyGPSPlus.h>
#include <NeoSWSerial.h>
/*
#define GPS_TX_PIN 4
#define GPS_RX_PIN 7
#define GPS_RST_PIN 8
*/
#define GPS_TX_PIN 4
#define GPS_RX_PIN 5
#define GPS_RST_PIN 14

// The TinyGPS++ object
TinyGPSPlus gps;

// The serial connection to the GPS device
NeoSWSerial GPS_Serial(GPS_TX_PIN,GPS_RX_PIN);

void setup() {
  pinMode(GPS_RST_PIN,OUTPUT);
  //GSM start
  digitalWrite(GPS_RST_PIN,LOW);
  delay(1000);
  digitalWrite(GPS_RST_PIN,HIGH);

  Serial.begin(9600);
  GPS_Serial.begin(9600);
}

void loop() {
  // This sketch displays information every time a new sentence is correctly encoded.
  while (GPS_Serial.available() > 0)
    if (gps.encode(GPS_Serial.read()))
      displayInfo();

  if (millis() > 5000 && gps.charsProcessed() < 10)
  {
    Serial.println(F("No GPS detected: check wiring."));
    while(true);
  }
}

void displayInfo()
{
  Serial.print(F("Location: ")); 
  if (gps.location.isValid())
  {
    Serial.print(gps.location.lat(), 6);
    Serial.print(F(","));
    Serial.print(gps.location.lng(), 6);
  }
  else
  {
    Serial.print(F("INVALID"));
  }

  Serial.print(F("  Date/Time: "));
  if (gps.date.isValid())
  {
    Serial.print(gps.date.month());
    Serial.print(F("/"));
    Serial.print(gps.date.day());
    Serial.print(F("/"));
    Serial.print(gps.date.year());
  }
  else
  {
    Serial.print(F("INVALID"));
  }

  Serial.print(F(" "));
  if (gps.time.isValid())
  {
    if (gps.time.hour() < 10) Serial.print(F("0"));
    Serial.print(gps.time.hour());
    Serial.print(F(":"));
    if (gps.time.minute() < 10) Serial.print(F("0"));
    Serial.print(gps.time.minute());
    Serial.print(F(":"));
    if (gps.time.second() < 10) Serial.print(F("0"));
    Serial.print(gps.time.second());
    Serial.print(F("."));
    if (gps.time.centisecond() < 10) Serial.print(F("0"));
    Serial.print(gps.time.centisecond());
  }
  else
  {
    Serial.print(F("INVALID"));
  }

  Serial.println();
}
