GPS Module blinking but not receiving any data with RPi 3

I am using a Neo-7M-0-000 GPS Module and the on-board LED is blinking, meaning it has a fix. But when I try to get the readings either through

sudo cat /dev/ttyAMA0

or through

cgps -s

It says "NO FIX".

I have connected VCC to 3.3V, GND to GND, TX to RX and RX to TX on a Raspberry Pi 3B.

Any suggestions would be greatly appreciated!

Solution

  • Point it to /dev/ttyS0 instead, AMA0 only on Pi 1 & 2.

    Make sure serial is enabled 

    sudo raspi-config

    P6 Interfacing Options

    No to enabling login shell

    Yes to enable serial port hardware

    Then run 

    sudo gpsd /dev/ttyS0 -F /var/run/gpsd.sock

    Test with cgps -s
