TinyDuino Processors & TinyShields / Re: GPS Data and Failure of Tinyduino to Turn Back On

Further to my post, I just reloaded the GPS code and went outside again. After checking the data on the SD card it now appears I'm not getting any satellite data at all. After running the data through a KML conversion program the resulting output was "Data found, but no GPS fix in your data". A sample of the SD card text looks like this:

$GPGGA,,,,,,0,00,,,M,0.0,M,,0000*48

TinyDuino Processors & TinyShields / GPS Data and Failure of Tinyduino to Turn Back On

« on: March 11, 2015, 08:38:33 PM »

I'm completely new to the world of Arduino having received my Tinyduino just yesterday. I got 'blink' to work which for a beginner is a nice simple way to start. I then thought I'd have a go at the "Tiny Arduino GPS Car Tracker with SD Card".
I had a few issues getting libraries and stuff to work on OS X which made it very difficult to work out why the tracker code wouldn't upload properly. However Codebender came to the rescue and I got it to work. But I do have a couple of questions.

When I attempt to upload the NMEA data from the SD card into Google Earth an alert box comes up saying "Loaded No Data". This happens every time. I thought that was odd so I jumped into the NMEA strings and extracted a line of code, converted it to decimal Longitude and Latitude and put that into Google Earth. Sure enough the GPS was unbelievably accurate - to within a metre. So it proved that some valid NMEA code was logged on the SD card. However, it appears Google Earth is not reading the file properly. I've reloaded the code a dozen times with the same result. Any ideas what the problem could be? I've attached the GPS data off my SD card from one of my attempts, if it helps.

Secondly, after unplugging the USB lead to my Mac and plugging in the LiPo battery, nothing appears to be happening with my Tinyduino and I'm assuming the GPS Tracker program isn't booting back up. The LED's don't flash indicating the SD card is being written to. I have to reload the code again, and to get it to work I have to have the battery already plugged in when I disconnect the USB lead. Any idea on what might be happening?

Thanks heaps.
