Default Does anyone have a DexCom?

Hi, folks.

My Dexcom came in the mail yesterday, and the numbers seem all over the place. I paired the device with my iphone, and it seems to lose the signal all the time. Also, I tried to pair it also with the receiver that came with it, but I can't seem to get it to work.

Has anyone ever paired it with both the iphone and reciever that comes with it?

I do! Your problem is not unique to you, I have the same problem constantly since starting on the Dexcom G5 and now the G6. My theory is that they have switched to Ultra Low Energy BT. I doing so, it greatly limits your flexibility. I use a T-Slim X2 insulin pump and an iPhone 6S Plus, to monitor my Dexcom. I have found that in order to make them all happy, I must keep the Dexcom sensor/transmitter, the pump and the iPhone on the same side of my body. If I move the pump or phone to the opposite side of my body, they will lose the signal. Moving them back to the same side eventually restores the connection. Also note that you only need to pair the pump, receiver and/or iPhone once. If you keep checking your phone for connection via BT, you will find that it isn't connected. This is because the transmitter only transmits a signal every few minutes, (5 I believe). So the result is your phone will not show as being connected, however, if your stay on the app, or keep the app active, it will monitor correctly. Once it confirms pairing, just keep the Dexcom app active. Don't close the app or it will lose connectivity. Hope this helps. Mike
