Yes, it's hard to get GPS lock inside

Comment by ARHEXA on March 27, 2011 at 11:45pm

I've read somewhere that some codes are not compatible with some versions of the GPS...

the GPS says MEDIATEK-V12. i'm using the RC2 code - are they good friend ?

does it need some special config in the code to turn the GPS on ?

No, don't use RC2.  Use the ArduPirates code instead and select MTK16 as your GPS.

OK,

I'm going here http://code.google.com/p/ardupirates/downloads/list

what should i download ?

and to i just put it in the arduino sketch dir and upload it like the RC2 ?

I've just spotted that "0.7071" appearing in the command terminal is part of the exact latitude i'm at.

but no signs for pars of the longitude (should be 34,50,13)

Comment by Kirill on March 29, 2011 at 3:47am

I had the same problem. I got only ............................ symbols and not any more.

I solved this problem by changing "GPS_PROTOCOL_MTK" with "GPS_PROTOCOL_MTK16" in apm_config.h.

My gps works even in the house not far from the window - about 4-5 meters.

Comment by ARHEXA on March 29, 2011 at 4:29am

solved by sending '4' instead of 'S'

Comment by Rebel K on March 29, 2011 at 9:23am

@ AR 

Could you please tell me how you've got those graphs (Outputs), that show the Roll, Pitch and Yaw.

Thanks !

Comment by ARHEXA on March 29, 2011 at 10:49am

It's on the configurator, just select 'raw sensor data'
