Re: [Paparazzi-devel] Paparazzi Stand Alone GPS also known as GPS13 not working

[David Conger]

Hello,

I see, well, yes, I am still away on a long overdue break. Honestly if
someone really needed some boards made I could work with a supplier to
get them assembled. It would just mean they add their markup to the
whole lot but I would be glad to help someone get what they needed
even while I'm away.

Yes, the old designs are still relevant and there is no reason that
board should just stop working other than I have seen them revert to
9600bps and the standard settings before. Charging the cap won't reset
the paparazzi settings back into it which is why I suggested using the
module in your airframe file. Even with no cap or a depleted cap it
should power up and work.

Have you used the tunnel before? Which autopilot do you have? I'lll
walk you through it if you like or call me I'll send you my phone
number and I can walk you through  it. I just am not sure if you've
done it before so I don't want to assume your level of experience with
these things.  The "Tunnel" is invaluable to me. That's still what I
do after all these years to test GPS after assembly.

If the instructions online are unclear let me know I've done it a
million times. I just don't have the computer I used in front of me
ATM.
