Grove GPS v1.1 - no connections to satellites

Grove is a modulated, ready-to-use tool set.
Much like Lego, it takes a building block approach to assembling electronics.

Grove GPS v1.1 - no connections to satellites

Post by psvas » Tue Aug 05, 2014 2:33 pm

Hello everybody

Recently I bought a Grove GPS module..
My problem is it won't connect to any satellites and the NMEA phrases are empty.
I use the code found on seeedstudio's wiki page and u-center 7.02.
http://www.seeedstudio.com/wiki/Grove_-_GPS

This is what I usually get back:
..
....
05:27:17 $GPRMC,052717.00,V,,,,,,,050814,,,N*73
05:27:17 $GPVTG,,,,,,,,,N*30
05:27:17 $GPGGA,052717.00,,,,,0,00,99.99,,,,,,*60
05:27:17 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30
05:27:17 $GPGSV,1,1,02,05,,,21,30,,,23*7F
05:27:17 $GPGLL,,,,,052717.00
05:27:18 $GPRMC,052718.00,V,,,,,,,050814,,,N*7C
05:27:18 $GPVTG,,,,,,,,,N*30
......
....
Sometimes I get the correct Longitude and Latitude for my position, everything else seems to be incorrect (GPStime, altitude, etc)

I am new to Global Positioning systems and very confused.
Am I doing something wrong?
Do I have to setup the module first?

can anybody help me out :?

looks like the ublox module takes a while to receive satellite data. I have experienced time ranges from 5mins to over 60mins before satellite was received. Time seems to come in earlier than long and lat.

Hi,

My Grove GPS was faulty, I got it replaced and the new one works fine.
I am VERY pleased by the customer support at SeeedStudio and http://www.exp-tech.de where I bought the module from.

With this Ublox module I noticed times from4-5 mins to 15min, but I tried it only few times at the same place, outside my window.
