I just found a whole package of Dexcom 7+ sensors in my closet that I forgot I had… does anyone know if I can make them work with the G5 transmitters? @Eric @mikep @docslotnick anyone?
Very unlikely. G5 (and G4) ran out of the box on the most updated Dexcom software (505). 7+ ran on the much older software and will probably not even communicate with a G4 or G5 receiver.
I’m going to go through my old boxes to see if I might still have an old egg receiver, 7 or 7+
EDIT: sorry, misunderstood. You want the 7+ sensor to talk to the G5 transmitter. My guess is still no. I seem to remember that the old sensors were not compatible with the G4 transmitter. But maybe an experiment is in store

No dice here. I’ve tried and it didn’t work with my G5.
