Well, After purchasing an external active antenna it looks like there is possibly an issue with the antenna on the gps board.
the active antenna is currently sitting on my desk in the middle of our office (nearest window 15 feet away) and it is now seeing 11 satellites on the u-blox test software. Now to try this on the omega itself.
You would have to look at the datasheet.
It has 2 serial interfaces.
I assume one of the serial interfaces is for data transfer while the other is for control.
So, if you use serial to USB converters, you should be able to connect both to an USB hub and connect the hub to the onion.
@Phil-John Sorry about that! I'm glad you were able to resolve the issue DIY-style.
We had defined testing and QA procedures for the GPS Expansion, however, the factory that manufactured the GPS Expansion did not follow our instructions. Needless to say, we are no longer doing business with them.
Thank you for your patience with us, we've definitely learned a LOT since the KickStarter campaign.
