I am following the directions from the learn section of the site, which demonstrates how to hook up an arduino uno and an ultimate gps board. https://learn.adafruit.com/adafruit-ultimate-gps
When I hooked it up directly to the computer and bypassed the microprocessor, I could read the GPS data clearly from the seal monitor. It appears GPS unit is functioning fine
But when I hooked up the gps to the arduino, as instructed, I get the following on the serial monitor , using the echo example from the Ultimate GPS library:
Jÿÿÿÿÿÿÿÿÿÿÿ_Þÿÿÿÿÿÿÿÿþÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
5v to Vin
Gnd to Gnd
3 to RX
4 to TX
Any suggestions would be greatly appreciated!

Re: Ultimate GPS and Arduino uno
Try changing the baud rate in Serial Monitor to 115200

Re: Ultimate GPS and Arduino uno
Thanks Rick. This worked great. I apologize for not seeing this in the code before.
Do you know of a way that I can send this data to GPS visualizer, so I can create a map dynamically as data is coming in? I will be using this GPS with 2 Xbee Pro's to track a balloon. Here is a website that talks about doing this, but I am not sure how to get the data to a document that has a url that can then be linked to GPS Visualizer.

Thanks again for your help

Re: Ultimate GPS and Arduino uno
You mean, you want to know how to generate the XML file format from the raw GPS data?
I think if it were me, I would simply pass the raw GPS data over the XBees, and then format the data on the receiving computer.
If you don't have a receiving computer, and you want to pass the XML formatted data over the XBees, then you'll have to write an Arduino program to perform the formatting. Perhaps there's a library out there which will do it for you - I don't know. That's a job for Google...

Re: Ultimate GPS and Arduino uno
Rick, yes, I want to pass the raw data over the xbees and then format the data at the receiving end. I will have a laptop at the receiving end hooked up to the Xbee. My concern is how to get the raw data into GPS Visualizer on Google earth. How can I export data out of the serial monitor in real time to a file that can be linked to GPS Visualizer. Would Tinygps program be an option?
Thanks
Thanks

Re: Ultimate GPS and Arduino uno
Serial Monitor would not be involved. The Arduino/XBee appears as a serial comm port on the receiving computer. You would need some utility that can accept standard GPS sentences from a COM port. Since GPS is a serial protocol, I would expect that you probably already have something that can accept GPS data. The fact that the data is coming over an XBee would be completely transparent.
