xDrip+ and re-calibration issues


Hi all, the calibrations I make sometimes don’t stick, which has been happening from the beginning of my xDrip+ use (a few months ago) – unfortunately I’ve always had to re-calibrate it at least once every few days (over a number of sensors), which is annoying but a tradeoff I would grudgingly be willing to make if necessary. Is there way to keep this from happening? I despise the Dexcom app but it did stay quite accurate over the full sensor life, so hopefully I can do something to get xDrip+ to stay that accurate without needing to re-calibrate and then worrying about whether I’m seeing the right reading.

This time I tried starting it up with the receiver at the same time when I started the newest sensor, but the issue remains.

I believe you can have XDrip+ use the same algorithm as Dexcom, or you can choose to use other algorithm’s. Are you using the Dexcom one?

Is that the “Native Algorithm” setting? If so then I do have that enabled, yes.



@Headlands if you are using XDrip in conjunction with a Tandem pump, you can force the calibration through the pump. On the next sensor push, XDrip will follow the pump calibration.

@docslotnick might also have suggestions. You could PM him…



@Headlands If the calibration does not sync up with the calibration table, xDrip+ will reject it on the G6. Sometimes the blood test does not even stay in the main screen graph as a small square.

If it really bothers you, you can turn off native mode and see if that helps.

As you can see, calibration is a different animal on the G6.



I think the calibration issue @Headlands is speaking about also exists on the G5, at least for me. If the Calibration figure is outside the expected scatter I get an Error 17/Rejected message. I just force calibrations through my pump so I don’t have to deal with the rejected calibrations.

I also use the Contour Next One which plots the data point regardless of XDrip’s rejected calibration. I generally add a contextual note so my care team has an idea of what’s going on when they examine the data on Tidepool.



What does that mean exactly: Sync up with the calibration table? I can’t trust it all of the time, which is dangerous, so if I can’t remedy it then I can’t use xDrip+ reliably…which would be awful due to the unbelievably poor Dexcom app.

I’ll try turning off native mode and see if that makes it work properly.

What Dexcom version are you using?
What version of xDrip are you using? Last stable was in January. Are you using a more recent version?

Without this info, who knows?
Sorry, but not nearly enough info to help you.

I stopped using the Dexcom app months ago and xDrip is whatever the latest version was 8 days ago when I downloaded and reinstalled from scratch, 1904011302.
