GETTING GPS LOCATION USING NEO-6M GPS MODULE
This tutorial introduces you how to get GPS location using stm32f4 and NEO-6M GPS module.
The Neo-6m GPS uses UART communication.
connect RX-(GPS)-TX(STM32F4)
connect TX(GPS)-RX(STM32F4)
The module will start receiving data when the red led starts blinking.
when extracting data, we want the sentence that starts with &GPRMC
""$GPRMC (Global Positioning Recommended Minimum Coordinates) provides the time, date, latitude, longitude, altitude and estimated velocity""
Sentence example
$GPRMC, 123519, A, 4807.038, N, 01131.000, E,022.4, 084.4, 230394, 003.1, W*6A
$ Every NMEA sentence starts with $ character.
GPRMC Global Positioning Recommended Minimum Coordinates
