To use the NEO-6MV2 GPS module with RPi

NEO-6MV2

Interact with neo-6mv2 GPS module for RPI

Here you have a description about the NMEA messages

And here more info about all the $GPxxx sentences.

NMEA messages implemented

• GPGGA
• GLL
• GSV

Build

Clone the repo on your rpi(3) and then:

$ make

Run

$ ./rpi_neo-6mv2_reader [serial]

e.g: $ ./rpi_neo-6mv2_reader /dev/ttyAMA0

lib usage

At src/neo-6mv2_reader.c file the code is commented in order to have an example for usage.

Tested on

• Raspberry Pi 3 Model B Rev 1.2 armv7l Linux6.1.21-v7+ ARMv7 rev 4
  • Raspbian GNU/Linux 11 (bullseye)
  • Raspbian GNU/Linux 12 (bookworm)

Setup UART

RPi3

• Edit /boot/config.txt and add: enable_uart=1
• To disable bluetooth; also at /boot/config.txt add: dtoverlay=disable-bt
• To disable the console for serial; Edit /boot/cmdline.txt and remove console=serial0,115200 and also:

sudo systemctl stop [e-mail]
sudo systemctl disable [e-mail]

• Reboot: $ sudo reboot

Connection RPI

NEO-6MV2	RPi
Vcc 3.3v	1 3v3 Power
Rx	8 GPIO 14 TxD
Tx	10 GPIO 15 RxD
GND	6 GND

Note: Rx conncetion between neo-6vm2 and RPi's pin 8 (GPIO 14 TxD) is not need it.

TODOs

• Not working at Raspberry Pi Zero W Rev 1.1 (Raspbian GNU/Linux 11 (bullseye) & Raspbian GNU/Linux 12 (bookworm)) armv6l Linux 6.1.21+ ARMv6-compatible rev 7 (v6l) (but hey! maybe it's just something going weird with my rpiZW ;)

NMEA messages

• GSA
• RMC
• VTG
