Question

我修改了Adafruit Fona GPS示例文件，以显示我的位置与其收集的GPS和GSM位置之间的错误。我输出的错误部分正确显示，但AT代码也显示在串行监视器上，我无法弄清楚如何抑制它们。代码如下，输出低于该值。我试图摆脱一切不是以＃34; GPS错误开始的行...＆＃34;。

float GPS_DIFF = sqrt((GPS_LAT - CURR_LAT)*(GPS_LAT - CURR_LAT) + (GPS_LON - CURR_LON)*(GPS_LON - CURR_LON));

输出是：

您正在使用Adafruit的库/函数，例如fona.getGPS，并且已编码为返回信息。

它可以在图书馆编辑＆＃34; Adafruit_Fona＆＃34;文件夹中。
