Long delay in CGM records

[YZR-M1]

Before explaining my issue I want to say how excited I am about the work you guys have started. This is really cool and something I have been thinking about since I got the G4. I have many ideas about how this could be used and have already implemented some of them in matlab, after writing data files with the python scripts. I don’t know much python yet, but might need to learn so that I can contribute to this project. Finally, on to my issue…

Typically when I use the python scripts to download CGM records ('EGV_DATA'), the most recent record is a couple hours old, and the delay is inconsistent. I have tested this on Windows and Linux. I always get 8740 records. The vendor’s SW (Decom Studio) shows me records that are only a few minutes old. Most of my envisioned uses would require up-to-date measurements. I scanned over the python code for requesting and parsing data and didn’t see any obvious problems, but again, I don’t know python. Does anyone else experience the same issue? Any ideas what can be done to fix it? Can I provide any additional information?

Good work! Thanks!!!!

I implemented a simple workaround which gets me the most up-to-date records, including CGM, meter, and events. Very happy now!!! Before reading the actual record data, there is a function call to get the available page range. The number of records in each page depends on the record type (CGM vs. meter, etc). To get ALL of the records I had to increase the page range by 1. This extra page is a PARTIAL page, i.e. it doesn’t contain the maximum possible number of records, like a FULL page does. My theory is the page range function returns only the number of full pages and excludes partial pages -- maybe by design or a bug. This software now does exactly what I wanted. Thank you very much!!! I have built a lot of code around your data reader and will likely start another git repo soon. Contact me if you want to collaborate.

I also ran into this issue. My workaround was the same. Just increase the max page by 1. As I was only interested in the latest day's records, I also reduced the range to just read the last few pages. This runs great on a Raspberry Pi. Thanks for the good work.

@YZR-M1 I'd love to see the work you've been doing in Matlab. I just wrote a couple small scripts to read CGM data to a file, then print using GNUplot (with start and end dates) but I'd really like to have some analysis of the data. My fork, with the print and plot scripts, is here.
