GPS Issue

Projects General Guidance

Hello Everyone,

I am using UBLOX Neo6mv2 GPS Module.
I recently interfaced the module with Arduino Successfully and I am able to extract the Lat/Long information perfectly fine.

Previously I was using an RTC module to time stamp all my data, but since that is inaccurate I want to use the GPS fix for time and date information.

I've ran into a dead end here. I used the following commands from this website: http://ukhas.org.uk/guides:ublox6
to disable all the NMEA sentences. And using the Serial.println("$PUBX,00*33"); command I am able to poll the GPS device for the information. I am unable to turn the NMEA sentences back on. I can't find any command online, even tried to read the protocol data sheet but it kinda went over my head.

The information I get when I poll the device does not contain the date, which I need for my time stamp, whereas the RMC NMEA sentence contains, date, time, lat, long information.

Basically, I want to know how to restore my device to default settings or turn back the NMEA sentences on periodically.

Here is the code used to turn them off:

Serial.println("$PUBX,40,GLL,0,0,0,0*5C");
Serial.println("$PUBX,40,GGA,0,0,0,0*5A");
Serial.println("$PUBX,40,GSA,0,0,0,0*4E");
Serial.println("$PUBX,40,RMC,0,0,0,0*47");
Serial.println("$PUBX,40,GSV,0,0,0,0*59");
Serial.println("$PUBX,40,VTG,0,0,0,0*5E");

Would really appreciate if someone could help me find the command to turn the sentences back on.

Thank You,

..tha same guide shows how to reverse the 'stop' command..

I can't seem to find anything on that guide to reverse it, maybe my mind is just unable to comprehend.

But I did manage to read the whole reference manual and found some propriety commands:

Serial.println("$PUBX,00*33);
//Position Fix
($PUBX,00,hhmmss.ss,Latitude,N,Longitude,E,AltRef,NavStat,Hacc,Vacc,SOG,COG,Vvel,ageC,HDOP,VDOP,TDOP
,GU,RU,DR,*cs<CR><LF>)


Serial.println("$PUBX,03*0D");
// Satellite Fix : GT = number of sats
$PUBX,03,GT{,SVID,s,AZM,EL,SN,LK},*cs<CR><LF>


Serial.println("$PUBX,04*37");
// Time and Day
$PUBX,04,hhmmss.ss,ddmmyy,UTC_TOW,week,reserved,Clk_B,Clk_D,PG,*cs<CR><LF>

So I think I will manage get all the data.

But it would be great if you could specifically point out where the reverse to the stop command is given.

Thanks.

Found this:

Reset to Default Settings:
The GPS module can be reset to its original default settings by pulling BOOT_INT high(3.3V) during a power cycle (Antaris Manual, p. 122). It may be required after a wrong firmware upgrade or a bad configuration change.
