  • Feature Request: Fast Fix for GPS

    Coyote,

    Is there a way to make an option that allows the GPS to begin trying to establish a fix before you ever go to the GPS menu? That way as soon as you go in, it could already have a fix. I mean maybe it already does this and my receiver is just not great. Anyway, whenever you get a chance if you could comment on this.

    I've got a feeling that they do this already.....the usb one's anyway. Maybe I'm wrong but I think the only thing that the computer or windows sends to the gps is the required voltage, which it must do on boot or windows wouldn't see the device.

    Mmmm, but do they start to look for sats before we open the port and read the data?? I may have to go for a drive... :-)

      Well from my testing, the GPS is dumb. It gets power and starts sending data. A software handler needs to be started and monitor the serial port and decode the messages. What I am asking for is if the GPS handler software that coyote uses can be started at the same time that mediacar loads.

          Is lock determined by software or by receiver?

            Got to be by receiver?? Software doesn't send anything as far as I know....just reads the strings I think!

              yes, all the USB GPS that I have tested try to lock directly after that it be alimented and begins to send the NMEA stream only when the com port is listened by a software.

              Listen to the port COM before will not change anything I think. When cold start, all GPS takes at least 40 seconds and don't waits to be listening to try to locks position.

                Yeah basically I was thinking that if you could make an option to start listening when the program loads then I wouldn't have to go to GPS menu. By the time I start playing some mp3s and go to the GPS menu it may already have gotten lock.

                  Video Lan for Media Car / Media Engine media player

                  Just a suggestion. Wouldn't it be a great idea to use VLC ( www.videolan.org ) as the video player for Media car/Medie Engine. You don't have to worry about Regions and it plays all different types of format?
