TinyDuino Processors & TinyShields / GPS board - Telit SE868 V2 - TinyGPS++ - Invalid data
« on: March 07, 2016, 08:13:34 AM »
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
