Arduino：尝试读取位置时出现 Neo 6M 问题

Question

我正在尝试让 Neo 6M 模块运行，同时我也在使用其他传感器。当我尝试单独测试 Neo 6M 模块时没有问题，其他模块也没有。

#include <TinyGPS++.h>
#include <SoftwareSerial.h>

// The TinyGPS++ object
TinyGPSPlus gps;

// The serial connection to the GPS device
SoftwareSerial gpsSerial(4, 5);

void setup(){
  Serial.begin(9600);
  gpsSerial.begin(9600);
}

void loop(){
  // This sketch displays information every time a new sentence is correctly encoded.

  while (gpsSerial.available() > 0){
    gps.encode(gpsSerial.read());
    if (gps.location.isUpdated()){
      Serial.print("Latitude= "); 
      Serial.print(gps.location.lat(), 6);
      Serial.print(" Longitude= "); 
      Serial.println(gps.location.lng(), 6);
      Serial.print("Altitude=");
      Serial.println(gps.altitude.meters());
      Serial.print("Speed=");
      Serial.println(gps.speed.mps());
    }
  }
}

与 Neo 6M 一起工作的代码

两个代码合并。

响应是：“1”，仅此而已。

你能帮帮我吗？
