GPS的数据格式是DDMM.MMMMMM

获取到的GPS帧数据比如是：$GNRMC,112317.000,A,3438.1633,N,11224.4992,E,0.19,186.95,240916,,,A*7D
说明
经度112°24.4992′
纬度34°38.1633′

OneNet支持的GPS数据经测试是DD.DDDDD,因此需要转换

经度为 112+24.4992/60 = 112.40832
纬度为 34+38.1633/60 = 34.636055

上传到GPS的数据流为

{"datastreams":[{"id":"location","datapoints":[{"value":{"lon":112.40832,"lat":34.636055}}]}]}

OneNet的GPS坐标是经过百度地图纠偏过的，所以这部分转换交给平台，直接上传上面的数据即可

 

用Arduino测试下转换计算过程：
