Trouble with raw GPS Tester / uBlox and 406 Tester

Hello All,

I have been having a fair bit of trouble with my ardupilot as of late. Previously, I had the 2.3 version of the code uploaded and working fine. Recently, however, I tried moving to the 2.5 code. Somewhere along the line I began having issues with the GPS finding a lock when it starts up. If I run the code in debug mode where it skips the GPS lock, it works as expected. I have tried running the Raw GPS tester code, and while I receive some output, it is not the expected output as described on the Wiki (I tested this with both an EM406 and uBlox). I also tried using both the uBlox and 406 test codes, and the only output I receive is the "begin GPS test". It appears to be stopping at the "if(Serial.available()>0)" command in the code, so I am assuming that it is not receiving any serial data.

I am currently using the ardupilot shield v1 and made the mistake of loading the code with the GPS still plugged in. I wouldn't have thought that this would cause any problems, but it may be an issue.

Thanks for any help or insight!

    Try plugging the GPS modules into the ArduPilot board, rather than the shield. Could be a bad connector pin on your shield. There's no problem with the code that I know of--works fine on my boards with both modules.
