GPS SENSOR

This sensor is intended for get the geographic coordinates received from UART NMEA 0183 compatible GPS sensors. A NMEA 0183 parser is included in the sensor driver that listens for GPGGA NMEA sentence.

Specification

What		Comments
Identifier	GPS	NMEA 0183 UART
Interface	UAR
Provides	lon	longitude (degrees)
	lat	latitude (degrees)
	sats	number of satellites
Properties	none

Code

gps = sensor.attach("GPS", uart.UART1, 9600, 8, uart.PARNONE, uart.STOP1)
while true do
   lon = gps:read("lon")
   lat = gps:read("lat")
   sats = gps:read("sats")
   print("lon: "..lon..", lat: "..lat..", sats: "..sats)
   tmr.delayms(500)
end
