Re: [Paparazzi-devel] GPS NoFix

Hi,

I've changed the airframe file to set the baud rato to 38400, but I
still do not receive gps signal.

Playing with the u-center I see that I only receive signal when the
baud rate is set to 9600. I even can not change the baud rate: I
change the rate and press send (as said in
http://paparazzi.enac.fr/wiki/GPS#GPS_configuration_using_U-Center)
but after closing and starting the u-center, I again see the baud rate
set to 9600.

Is there any problem with working with 9600 baud? How could I set the
tiny / GCS to work with 9600 baud rate?

And the most important thing. Why cant I change the conf of the GPS? I
think maybe I have an old firmware? Does anybody have firmware for the
LEA-4H

Kind regards,
Santi.
