Hi Team,

We have created an application which will fetch GPS co-ordinates and continuously publish the location of the device using MQTT publish.  
The issue is we are not able to get location details, see below snippet

```auto
le_pos_GetFixState();
le_pos_sample_Get2DLocation()

```

Here, the FixState() api is returning -3 as error. Which means the position is not fixed.

Then we tried using `gnss` commands and tried to get position.  
`gnss get posInfo` is returning Position not fixed  
Then tried: `gnss fix` is returning **TTFF not calculated**.

Tried also with at commands: AT!GPSTRACK, AT!GPSSTATUS, AT!GPSSATINFO…  
**at!gpssatinfo?  
Satellites in view: 2 (1980 01 06 6 00:00:00)**

 
 **- SV:255 ELEV: 0 AZI: 0 SNR: 27**
 - **SV:255 ELEV: 0 AZI: 0 SNR: 28**

We got to know minimum of 3 to 4 SATS are required for getting fixed location.

I am not able to resolve this issue.

Please help me with this?

Thanks,  
Pallavi B.

In MS-based mode in AT!GPSFIX, 4 or more SVs are required to generate a fix.

Can I know what are all the different ways to get device position info other than GNSS???

</div>

do you have a SUPL server?

you need to use AT!GPSSUPLURL to set up  
after that you need to use “MS-assisted only” mode in AT!GPSFIX

Hi jyijyi,

we have [supl.google.com](http://supl.google.com) server or [supl.nokia.com](http://supl.nokia.com) server. Can we use those?

I used google SUPL server before, but later, it cannot be used publicly.

You need to do some testing.

Good luck!

Before using this command “AT!GPSSUPLURL”, do we need to set any other commands.

Check “GPSENABLE” in AT!CUSTOM?  
Also check “AT!GPSSUPLVER” and AT!GPSTRANSSEC

</div>

are we using same FW R13.3?  
Does it work after typing at!gpsend=0 ?  
did your module register network and obtain IP address?

Does at!gpsfix work on  
• 1=Standalone (not supported by a mobile station)  
• 2=MS-based only

You better take another module for testing
