I use WP7605 for the module. And I am trying to get location information with the Location API.  
AT command AT! GPSFIX has a parameter called (Requested accuracy of fix).  
In other words, you can set the minimum precision required for FIX data.  
However, I could not find this setting in the Location API and GNSS API.  
Is there a way to set in Legato?  
Is there a latitude / longitude maxDist value returned from legato’s le\_pos\_Get2DLocation () and le\_pos\_Get3DLocation ()?

I don’t see one legato API having this “maxDist” to configure.

Hi jyjyi-san

I examined the correlation between AT! GPSFIX parameters and SUPL\_START qoP values.  
Apparently, the SUPL server provides assist data when the qoP value is 19 or less, and responds to the base station latitude and longitude with SUPL\_END without assist data when the qoP value is 20 or more.  
However, when starting MS-Based A-GPS with **Legato’s API, the qoP was fixed at 49**.  
In other words, it is not possible to obtain assist data with A-GPS using Legato API.  
Please provide a solution on how to work with qoP values below 19 when using A-GPS with Legato applications.

■WP7605  
(SUPL qoP) vs (AT command)  
horacc 19, AT!GPSFIX=2,1,1  
horacc 19, AT!GPSFIX=2,1,10  
↓ Does not provide Assist Data from SUPL Server ↓  
horacc 42, AT!GPSFIX=2,1,100  
horacc 49, AT!GPSFIX=2,1,1000  
horacc 49, AT!GPSFIX=2,1,10000  
horacc 49, AT!GPSFIX=2,1,100000  
horacc 49, AT!GPSFIX=2,1,4294967279  
horacc 49, AT!GPSFIX=2,1,4294967280

how about sending those AT command in legato application?
