Insert BG as CGM not working while pump battery is low. #193

Closed th122 closed 5 years ago

th122 commented 6 years ago

Tried to activate "Insert BG as CGM" as an experiment to get a current value into xDrip during the warm-up phase of the sensor, but nothing transpired.

Could this be due to not asking for history while battery is low? (Battery was reported as low just after arriving at work, hope it'll last a little bit longer. )

Your Environment

Brief Explanation of Issue

Uploader Log excerpt

(typed from screen)

btw: is there a way to access the log file-wise? The messages don't seem to trickle into system logs.

Steps to Reproduce (for bugs)

  1. Activated "Insert BG as CGM" setting
  2. disconnected meter, took bg reading, reconnected meter
  3. Uploader detected reconnected meter and initiated read
  4. recent BR read discovered, but no value displayed or communicated anywhere.

Severity Score

1 -- While the feature is great, expecially when there's no sensor readings (or no sensor at all) it's hard to miss a bg reading, so the only impact is on data analysis, not on care.

This is by design to reduce the use of the pump battery.

You can override this by setting the low battery poll period to the same as standard poll period ie. 5 mins.

th122 commented 6 years ago

Wouldn't that still not get the bg, since it's asked off the pump history, and - as far as I thought- the pump got polled anyway because of the "meter reconnected" event but the historical data didn't get requested to save energy? In case of low pump battery, maybe asking the meter bg directly instead of the meter bg data as stored in the pump might be an option. (And given the length of my day at work, I'll gladly let the uploader conserve energy :-}

When the poll period and low battery period are set to 5 mins it will only show a warning and not try to conserve power. We don't do anything with the meter only the pump as that's out of the scope of this project. I have low bat poll at 5mins as I find it can run 12-24 hours when it gets to this level but YMMV. Always keep a spare battery with you in your day supplies as the pump can sometimes fail a battery even before it's lifetime is up, sometimes it will even fail a fresh battery.

Thanks for that warning, I wasn't prepared for sudden battery failures (or rejects)! I'll reset the low battery poll and try again, then, thanks!

th122 commented 6 years ago

Great! yes, with low battery poll at 5 minutes it does retrieve history. It didn"t even detect the BG reading though, this time. (Might be a timing issue: The pump has the BG data with a timestamp of 15:54, the meter got reconnected right after it confirmed "sent", and the reading has a timestamp of 15:53. Subsequent requested polls at 15:55 and 15:58 didn't pick up the BG reading. I'll give it another try with some more time before reconnecting the meter. Have to be quick, it'll ask for calibration any moment now.

th122 commented 6 years ago

Didn't work either:

(Now the pump requested calibration. Of course it asked to snooze the alarm instead of picking up the BG it got sent about 90 seconds ago {-8 )

Pogman commented 6 years ago

sounds like the pump dropped it from it's history - or just bad timing. If it's in the history it will show up next time but you might just want to try getting your bg again.
