在arduino uno上使用带有单独gps屏蔽的gsm / gprs屏蔽

标签： gps arduino

我一直试图从我的gps盾牌获取gps数据，然后使用arduino uno上的gprs shield发送到Web服务器无济于事。 我正在使用Seeduino的gprs shield v2.0b与sim 900和gps v1.1盾牌。 我能够单独获取gps数据并单独发送到我的Web服务器，但在两者结合后，它将完全停止工作。 两者都使用软件序列，但在不同的端口上。

我的整个代码位于

之下 
#include "SIM900.h"
#include <SoftwareSerial.h>
//#include "inetGSM.h"
#include "sms.h"
//#include "call.h"
//#include "gps.h"
#include <TinyGPS.h>
//#include <String.h>


//To change pins for Software Serial, use the two lines in GSM.cpp.

//GSM Shield for Arduino
//www.open-electronics.org
//this code is based on the example of Arduino Labs.

//Simple sketch to start a connection as client.
/* This sample code demonstrates the normal use of a TinyGPS object.
 It requires the use of SoftwareSerial, and assumes that you have a
 4800-baud serial GPS device hooked up on pins 3(rx) and 4(tx).

我们遇到了同样的问题。我们通过切换到AltSoftSerial解决了这个问题。有一个工作跟踪器的演示，在我们的网站上有代码 http://www.mallinson-electrical.com/shop/gpsgsm 我希望这有帮助
