Hi,

I've just got myself a new GPS board - using the Telit SE868 v2 chipset.
I've tried several sketches and get varying results.
Using the link from the product page to TinyGPS++ I was able to download the libraries and use them to test the unit.
http://arduiniana.org/libraries/tinygpsplus/
-

I've not been able to get the example code to work - everything implies the data is either invalid or failing the checksum tests.
I've used the "Full Example" as a base.
Originally I was only getting *'s, removing the check for Valid data before printing allowed me to see a little more, but nothing useful.

Everything implies the unit isn't providing correct data - but I'm finding it hard to track it down.

Does anyone have any success working with these GPS units?

Thanks,

Jeff

I had a variation of this code running on my dashboard on the drive to work - only the windscreen in the way.
Nearly and hour journey and still no valid data received.

Sorry about this problem and the delay responding- You've logged raw data like the second post outside and not seen a NMEA sentence with real data within a few minutes(depending on weather)? We'll definitely replace it if that's the case, please send an email to info@tiny-circuits.com referencing this post.
