The challenge: Decoding the Dexcom STS data format

I've loaded several data files from the Dexcom STS Software on this server.

If you want to help in decoding the Dexcom data format, I hope these will help you.

1. Sample Dexcom data file.
   This contains a small amount of data. I reformatted the file for readability.
2. Second sample Dexcom data file.
   This is the first file created when I read data from the Dexcom transmitter.
   It should contain all data items supported by the Dexcom software, there seem to be four of them.
   And there's a lot more data in this file because it was downloading a few weeks of data.
3. Text representation of some records from the second sample Dexcom data file.
   Using the Dexcom software I looked at the first records that are probably in the data, and captured them in this text file.
