No the libre definitely doesn’t connect to the 640g, so you would think the cgm would be the only way to go. Reading other posts though, a lot of thumbs down for the cgm in regards to connectivity problems.
My hypos aren’t severe or often so I’m not really worried about the basal suspend at the moment. I went through that for the first 5 months as a pump user (I’m sure my a1c was 3.0!) but we dialled the dosage way back and now I run a little on the high side. This is apparently to get my hypo awareness back to where it should be. That and the fact I do so many various tasks (shift work, desk work, mechanical, cattle property work), means I have a lot of different basal patterns. So trying to dial in each pattern seems to take forever! So far I have the night shift pattern and the at home with the wife and kids playing pattern pretty well perfect. Work and any manual labour patterns we are getting closer to but for now it’s live on the high side and work it out from 6-8 tests per day without cgm. PS, I am located in north Qld as I forgot to say that before.
