NMEA is the abbreviation of National Marine Electronics Association (National Maritime Electronics Association. The Association is a private institution dedicated to research on marine electronic devices and has developed NMEA standards for communication interfaces and protocols between GPS (GPS) electronic devices. NMEA-0183 protocol is currently the most widely

To share with you, but also for the future will not forget.NMEA protocol in general, relatively simple, is a relatively mature weather protocol.There are several main parameters and their formats: Wind speed and wind direction; Air temperature; Soil te

NMEA is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent ASCII format that separates data streams. The data stream length ranges from 30 to characters, the output is usually selected at intervals per second. The most commonly used format is "GGA". It contains the positioning time, latitude, longitude, height, number of satellites used for positioning, and other

1. Two ways to add, The first of these methods If it's a music file, we connect the ipad directly to the computer, then we open the itunes software, just drag the music from the computer to the itunes Music channel, and then sync it to the ipad.
