    Arrow Nokia N95 GPS question

    Hi,
    My name is Michael and a last year student.
    As a final year project am developing a J2ME application that uses the Location API and its implemented on Nokia phones especially N95 8GB.
    My question to you sir is,
    everytime i do a Location request from N95 device i get the "exception error : Location Request timed out"
    any idea why this is happening and how can i solve it?
    Does the application need to authenticate the sattelites before retrieving the co-ords and if so how to ..?


    Any idea or tip would be deeply appriciated.

    Thank you in advance
    Michael

    Have you turned on the GPS through the phone settings?
    Does that GPS have a fix to the satellites yet?

    Hi there, I do have the same problem too. However, I cannot even get any satelite connectivity even from Menu-Tools-Connectivity-GPS data.

    Re: Nokia N95 GPS question

    Alright i managed to do it by just coding another line such as:

    " c.setCostAllowed(true); "

    This might be the solution to my problem it might not.

    Anyway my application is up and running.

    Thx all for the help and guidance.

    Regards

    Re: Nokia N95 GPS question

    Hi, I'm a 3rd Year student at a polytechnic. I'm curently also working on a GPS application for my third year project. Before implementing my project into a N95 phone, i managed to get the coordinates and the positioning of the location through sps file/ nme file.
    But the problem is, does this mean that everytime i want to change the location i need to change the SimPSYFilename? Or i dont need any nme file once i implement it into the phone?

    Anyone can help me with this? Any help would be really appreciated as this is pretty urgent. Thanks alot

    Re: Nokia N95 GPS question

    I have the same problem. Timeout error.
    I can't even run GPS in default tools, because it doesn't show anythings.
    Perhaps built in N95 GPS are defective?!

    Erm... keep the numpad open at a 45 degree angle to the clear sky in case you were trying to retrieve a signal from indoors.

    I dont know if GPS receiver on N95 are defective.

    Re: Nokia N95 GPS question

    hi,
    i have n95 8gb, but my compass in GPS data is not working properly.

    it's upside down, instead NORTH it's showing South. i'm moving the device to the left or to the right but he is not responsing (compass) , or it is very slow. it will show north properly and for quicktime its upside down again, sometimes shows west instead north.

    also if i put navigatiot to the landmark it is showing that i should go to the opposite way.

    satellite status is OK, 4 or 5 satellits

    what can i do? help
    thanks in advance

    Re: Nokia N95 GPS question

    That is not a real compass, the phone does not have such a sensor to allow detection of orientation changes.

    The application calculates the orientation after determining your position in consecutive measurements. Just start moving in some direction or another and the compass will show more accurate information.

    P.S. Since this is your first post on the forum make sure you read this.

    Re: Nokia N95 GPS question

    Hi Guys,

    Dont know if this will help but i have been creating a LBS app and when you create a location provider just make sure that you set no limitations on the criteria object such as "cr.setCostAllowed(false)" as this will cause the app to work on the emulator and not on the device itself try something like this

    public void lp(){
    criteria=new Criteria();

    try{
    locationprovider = LocationProvider.getInstance(cr);
    }
    catch(LocationException le){

    }
    }
    public void sl(){
    locationprovider.setLocationListener(this, 2, -1, -1);
    }

    Hope it helps
