I’m currently using the G5 (I’m on Medicare). I run xDrip+ on my phone and the Dexcom receiver (I’m retired with plenty of time on my hands).
XDrip+ does not recognize that the sensor is expired, it just keeps going. The strange thing is the Dexcom receiver is doing the same thing, except with a 2 hour warm-up!
The receiver told me my sensor session was over, so I just tried the “start sensor” button and it went
into the warm up. Two hours later it asked for double calibration and I gave it two readings. It has been giving readings for 7 days+24 hours!
No microwave or Faraday bag involved. The receiver was in my shirt pocket the whole time.
This makes me rethink the communication between devices.
