it's still reading it nearly 10 hours later
Lol, db89, that takes me back to when I first used it!
I can't remember now whether it's the blucon or xdrip, probably xdrip, but it pulls another 12 hrs out of libre and then end of.
First time I saw it happening, I was thinking, godarn, it's still running - for how long, a day, a week? But, nah, 12 hrs then that's it.
I was paying for libre back then, so it was a big deal getting more out of it. I'm on script now, but I still run the extra 12 hours just on a point of principle - don't chuck away some free stuff.
There's a point I forgot to mention to do with changing sensors when using xdrip and blucon.
We've got the calibration gig in xdrip. It calibrates with the sensor you're using. Change the sensor, what happens next?
You put blucon on the new sensor, it'll pick up on the next 5 min read and send to the phone. Blucon has no idea it's on top of a new sensor.
I don't know to what extent xdrip reads back to look at much earlier calibrations.
Maybe it makes no difference at all if you've got a day old new sensor but still have two week old readings on the calibration graph.
Because I'm not sure about that, I err on the side of caution and clean out the calibration graph at the start of each new sensor so that the whole show is starting afresh. I'll do that sometimes too if the current sensor is sketchy and takes time to settle.
Couple of pics to illustrate. Go into Settings, Stop Sensor, click "Don't stop, just reset all calibrations".
That cleans out earlier cals which you've done for earlier sensors so you get a brand new graph for the new sensor to work from.
It then asks you for a couple of new bg readings.
If that's not done, you just end up with an incoherent cloud of white dots from weeks worth of earlier sensors. Like I say, I don't know whether it actually makes a difference - maybe it ignores much earlier ones, I don't know.
There's also the calibration data table to play with. You can long press to delete dubious cals, but I'm just playing guessing games with the utility of that at the moment.
