Dexcom G6 Backfill data requirements

[loopy321]

Any idea whether it is possible to get backfill data from a G6 81XXX transmitter (and what is required)?

I suspect I am not getting backfill because the "Use Transmitter Algorithm?" setting is off, but wanted to make sure I was not missing something...

Also, with "Use Transmitter Algorithm?" off, it looks like I am running in "raw mode" with calibrations and shows "Sensor Start" as under "Bluetooth" page, even though when I click the "..." on the "home" page gives me a start time.

Thanks!

Figured this out. Need to use Transmitter Algorithm, which apparently requires a stronger battery than the older style connection.
