将 AdafruitFona GSM shield 与微型 gps 库集成

Question

我需要帮助来整合这两个库，以便我可以通过 GSM 发送 GPS 数据。需要有关使用两个特殊序列的信息，还需要代码帮助。

下面的 segmnet 包含 GPS 屏蔽的代码，必须使用它来生成位置，并且必须通过 gsm 将此数据发送到手机号码。

#include <TinyGPS++.h>
#include <SoftwareSerial.h>
/*
   This sample sketch demonstrates the normal use of a TinyGPS++ (TinyGPSPlus) object.

Answer 1

这是混合使用 GPS 输入设备和 GSM 输出设备的分步说明。

Remainder for Arduino principles:

The void setup() function is performed one time after startup.

The void loop() function is performed periodically after the setup().

第一步 - GPS 设备和序列号声明 link

// GPS and Serial link
static const int RXPin = 4, TXPin = 3;//was 4 and 3;
static const uint32_t GPSBaud = 9600;
// The TinyGPS++ object
TinyGPSPlus DeviceGPS;

// The serial connection to the GPS device
SoftwareSerial SerialGPS(RXPin, TXPin);

第 2 步 - GSM/FONA 设备和序列号 link

的声明

Including the SendTo SMS number !!!

#define FONA_RX 2//2
#define FONA_TX 3//3
#define FONA_RST 4//4

// The serial connection to the GSM device
SoftwareSerial SerialFONA = SoftwareSerial(FONA_TX, FONA_RX);
// The FONA/GSM Cellular Module device
Adafruit_FONA DeviceFONA = Adafruit_FONA(FONA_RST);
// The destination SMS number
static const char *sSendTo = "<NUMBER>";

第 3 步 - setup() 函数（控制台、GPS 和 GSM）

It is possible to add some extra Init.

// only execute once
void setup()
{
    // Wait and Init Console
    while (!Serial); // Serial over USB
    Serial.begin(115200);

    // Init GPS link
    SerialGPS.begin(GPSBaud);
    Serial.print(F("TinyGPSPlus ver: "));
    Serial.println(TinyGPSPlus::libraryVersion());

    // Init GSM link
    SerialFONA.begin(4800);
    if (! DeviceFONA.begin(SerialFONA)) {
        Serial.println(F("Couldn't find FONA"));
        while (1); // Stop working
    }

    // Add some extra Init      
}

Step4 - loop() 函数等待 GPS 定位并发送短信

It is possible to use String() to create the SMS based on the acquired DeviceGPS.location.lng() and DeviceGPS.location.lat().

// executed periodicaly
void loop()
{
    // check until GPS message
    while (SerialGPS.available() > 0) {
        // get for a complete GPS message
        DeviceGPS.encode(SerialGPS.read());
    }

    // flush GSM serial link
    while (SerialFONA.available() > 0) {
        if (DeviceFONA.available()) {
            DeviceFONA.flush();
        }
    }

    // send an SMS!
    char sendto[21], message[141];

    // Wait for location (lng, lat, alt) is OK
    if (DeviceGPS.location.isValid()) {
        // ==> create SMS with longitude & latitude

    }   

}
