I find, like most others posting here, yes I do and it is positional. To minimize the problem, I usually place my sensor toward midline and on my torso…so if I roll to one side or the other - more likely to still communicate with my receiver. I am a side and back sleeper. Still using the receiver despite upgrade to G5. I don’t lose signals often enough to warrant wearing the receiver in a piece of clothing…like we used to do w/ tubed pumps, but I guess that would work.
Just curious, when you guys lose connection–does it have the ???, or no signal? I have found that if there is a large change in readings (caused by pressure on the transmitter) the receivers (both receiver and iOS device), it will stop transmitting for a duration of time. Usually it will correct itself–but this is probably in place as a data validation safeguard. Basically–if you are getting very volatile numbers, the device senses a problem and doesn’t transmit possible erroneous numbers.
Let me know.
I’m, trying to find, out what makes, my transmitter lose, it signal, so, i going keep my, eye on this Topic, i try anything,.
Hi Anthony, do you have any more info on this? I’m in South Africa and have the same issue with my daughter’s. It either just stops sharing or start saying signal loss. Driving me crazy as it only happens at night.
My issue was actually not a signal loss. The iPhone app would shutdown in the middle of the night, and it wouldn’t start monitoring again until manually started the G5 Mobile app. This has since been resolved since Dexcom released the last update to the app. That was sometime in January I believe. Do you have the latest version of G5 Mobile app?
I’m going to check that we have the latest version. My daughter’s app always stops sharing at night. Thanks for the help!
Do you get ??? or no signal?
I’ve found that “no signal” indicates a problem with the transmitter/receiver and ??? usually indicates that pressure on the sensor against the skin will cause a false high/low and confuses the readings–causing the ???. It usually takes a bit of time to recover from that event.
My husband is on the Omni pod and Dexcom G5 CGM. We have had lost signals all over the place! He’s had hypoglycemic events and the lost signal has kept it from alarming. EVERYTIME I call Dexcom tech support, I get a different answer to what is causing the problem. My husband has his receiver and iPhone sitting at waist height on a tv tray right next to his side of the bed. He sleeps on his back almost always all night long. I am about ready to toss the entire Dexcom CGM in the trash! I am a medical professional and this thing is great when it works and worthless when it loses signal. I am glad I found other people having the same problem. I just wish Dexcom did more than say they don’t know why it is happening. Anyone know of the answer since Dexcom doesn’t seem to?
Perhaps you are getting different answers from Dexcom support personnel because there is more than one cause of signal loss. To name two, immersion in water can cause signal loss. Putting too much pressure on a sensor by rolling over onto it during sleep can cause signal loss (in addition to “pressure lows”). I am sorry your husband is experiencing so many lost signals. My daughter has a handful of dropped signals on some days, but readings usually resume within a relatively brief time and we are quite pleased with the Dexcom G5.
We have experienced lost signals for anywhere from a few minutes to over 2
hours. I don’t mind a short one but when they are during the middle of the
night and he is hypoglycemic, I a furious! We have only been on Dexcom for
about 6-8 weeks.
I have the “No Data Notification” alert on my iPhone (which I keep within hearing distance 24/7) set to sound once I have received no data for 45 minutes. Once I’ve gone that long without a BG reading, I go old-school and do a fingerstick on my daughter. If you set your “No Data Notification” accordingly, you will not need to go for over 2 hours without knowing your husband’s BG. You can set this alert to sound as frequently as every 30 minutes.
We don’t have the iPhone app (we are Droid users in this house!), but we have had the signal lost at different times… most of the time it’s due to the transmitter being “rolled onto” or otherwise in such a position that it can’t send out a signal to the receiver. In the night when I see this, I flip my son over so that the transmitter is visible again and it begins recording again on the next tick mark. I have done an immediate finger stick just to be sure sometimes if it’s been out for a while.

Linda, does the Dexcom receiver also lose its signal? Or just the iPhone?
Both.
And where is the sensor placed on his body?
Yesterday our local Dexcom rep came to talk with my support group and this question came up. This problem has been reported by a number of people and it was suggested that powering down and powering up the iPhone on a daily basis may help this problem. This was exactly what @anon85331563 reported.

I was told by Dexcom rep that the receiver and iPhone cannot be used at the same time. Turn the other off then start the other device. I use xdrip now on android and it has the same restriction, that is, the receiver can’t be used while using xdrip when they both devices are located within Bluetooth connection.
how odd. My daughter and I have had the opposite experience, we are both use a Dexcom G5s and keep our receivers and Iphones on at the same time without issue. At night we keep my daughers Iphone and receiver next to her bed within a few inches of each other.
@Danny_ one thing that I’ve seen effect signal is if the dexcom is compression. Could you be sleeping on it?
When I first began using the G5 I also used both the iPhone and receiver and had no problem.
