通过 GSM 模块发送 GPS 位置
Sending GPS location via GSM module
我正在使用 SIM900A GSM 模块和 NEO-6m GPS 模块。我想在GSM模块收到消息时,通过GSM模块发送位置。
当我在 GSM 模块的帮助下接收和发送任何消息时,我的代码可以正常工作,但是当我加入这两个模块(即 GPS 和 GSM 模块)时,它就不起作用了。
这是我的两个代码。
#include <SoftwareSerial.h>
// GPS
#include <TinyGPS.h>
// GSM
SoftwareSerial SIM900A(9, 10);
SoftwareSerial mySerial(5, 6);
TinyGPS gps;
void setup() {
Serial.begin(9600);
SIM900A.begin(9600);
SIM900A.println("AT+CNMI=2,2,0,0,0");
mySerial.begin(9600);
delay(1000);
}
void loop() {
bool newdata = false;
String buffer = readSIM900A();
if(SIM900A.available() > 0)
Serial.println(SIM900A.read());
if (buffer.startsWith("\r\n+CMT: ")) {
// printing the number
Serial.println(buffer.substring(9, 22));
// Remove first 51 characters
// buffer.remove(0, 51);
int len = buffer.length();
// printing message
Serial.println(buffer.substring(51, len-2));
if (buffer.substring(51, len-2) == "location") {
Serial.println("Sending location");
// GPS
if (mySerial.available()) {
char c = mySerial.read();
if (gps.encode(c)) {
newdata = true;
}
}
if (newdata) {
long int lat, lon;
unsigned long age, age1, date, time, chars;
gps.get_position(&lat, &lon, &age);
gps.get_datetime(&date, &time, &age);
Serial.print("Lat/Long(10^-5 deg): ");
Serial.print(lat);
Serial.print(", ");
Serial.print(lon);
Serial.print(" Fix age: ");
Serial.print(age); Serial.println("ms.");
Serial.print("Date(ddmmyy): "); Serial.print(date);
Serial.print(" Time(hhmmsscc): ");
Serial.print(time);
Serial.print(" Fix age: "); Serial.print(age);
Serial.println("ms.");
Serial.print("Alt(cm): "); Serial.print(gps.altitude());
Serial.print(" Speed(mps): "); Serial.print(gps.f_speed_mps());
// setting GSM module
SIM900A.println("AT+CMGF=1"); //Sets the GSM Module in Text Mode
delay(1000); // Delay of 1000 milli seconds or 1 second
// sending location from which code word had come
SIM900A.println("AT+CMGS=\"" + buffer.substring(9, 22) + "\"\r");
// Replace x with mobile number
Serial.println("AT+CMGS=\"" + buffer.substring(9, 22) + "\"\r");
delay(1000);
SIM900A.print("Lat/Long(10^-5 deg): ");
SIM900A.print(lat);
SIM900A.print(", ");
SIM900A.print(lon);
SIM900A.print(" Fix age: ");
SIM900A.print(age); SIM900A.println("ms.");
SIM900A.print("Date(ddmmyy): "); SIM900A.print(date);
SIM900A.print(" Time(hhmmsscc): ");
SIM900A.print(time);
SIM900A.print(" Fix age: "); SIM900A.print(age);
SIM900A.println("ms.");
SIM900A.print("Alt(cm): "); SIM900A.print(gps.altitude());
SIM900A.print(" Speed(mps): "); SIM900A.print(gps.f_speed_mps());
SIM900A.println((char)26);// ASCII code of CTRL+Z
delay(1000);
}
}
}
delay(100);
}
String readSIM900A() {
String buffer;
while (SIM900A.available()) {
char c = SIM900A.read();
buffer.concat(c);
delay(10);
}
return buffer;
}
以上是我在GPS和GSM模块一起处理时的最终代码。当它们分开处理时,它们工作得很好。
连接数:
将SIM900A的Tx、Rx引脚分别接到Arduino Nano的9、10,将GPS模块的Tx、Rx分别接到5、6。我还与 Arduino 建立了共同点。

P.S : 我已经更改了 GSM 的引脚,其余部分相同。除了添加 AltSoftSerial
它是一个与 SoftwareSerial
相同的库(从管理库下载它,它需要引脚 8 和 9)。不要更改草图中的引脚号更改连接。
