How would you characterize your experiences with connectivity with your current Bluetooth-enabled diabetes devices?

Ordinarily, I never had an issue with BT connectivity. But when Tandem Mobile Bolus came out for Android phones, the pump and android would randomly drop connection between them. There is a hack that gets around the issue, but uses more battery on the android phone. I am sure T-Connect will resolve the issue so the hack is not necessary. So far still using it. If I download a new T-Connect app from play store, I will remove the ‘fix’ and see if is resolved
When my Android device went from Android 12 to Android 13 around October 2022, my G6 would almost never connect. I had to buy a cheap phone running Android 8 just to use for CGM. The problems were resolved with the December 2022 Android update. Since then, I’ve had no issues.
Started the G7 last month. Have connectivity problems frequently. Not for long. My new device last night, I tried to avoid waiting the half hour warmup, it worked but had false low readings all night. Finally turned off phone. Won’t do that again. Didn’t have a problem when I waited for the warm up period.
Interesting timing. up to a month ago I would’ve said infrequently, but ever since I switched to the Omni 5, my Dexcom has been giving me the “wait 3 hours” error way more often than before. I’m wondering if it’s something to do with multiple devices connecting via bluetooth? Or maybe I just need to dump the existing transmitter? It expires this month and I have had transmitters get wonky as they near the end of the three months. Hoping that’s it and it’ll all resolve.
I had the same problem a few years ago with my Samsung A71 phone and my Dexcom bluetooth device. It went on for months. I never was able to resolve it, and just dumped the Dexcom program. Later on, I downloaded the T:connect program, and have not had that problem.
I have frequent connectivity issues between my T:Connect program on my Samsung A71, 5G phone, and my Dexcom G6 sensor (along with my Tandem X2, Control IQ pump. Now, a lot of the problems is me, because I am not “connected at the hip” with my telephone. I purposely keep my phone a distance from me, but near enough so I can hear it ring. That causes many connectivity issues. I found that if I turn off the app, then re-open it, it resolves the connectivity issue, 90% of the time. There are occasions when it just won’t connect. I have to try at a later time. When I don’t have a connection, I just look at my pump for my information.
My Tconnect app regularly disconnects from my pump. Thisis the message:
A bluetooth error occurred when your phone tried to communicate with your pump. To resolve it, you need to unpair your pump form the app and pair your pump again.
I’ve done the unpair/repair thing, and it works for a time, but I don’t bother anymore since I get the info I need.
Anyone know why it does this so frequently?
PS I have a Samsung Galaxy S20 FE 5g
My cell phone messes up a great deal of the time. I would never rely on device connectivity for my t1d’s important issues.
I have a Samsung Galaxy S22. Everyday I have go through the process of reconnecting the bluetooth on medtronic app. Sometimes twice a day. Hopefully Medtronic will fix this.
I had a few times wherenthe T:slim and my phone loose paring. I had to watch the video about 3 times to get the repairing to work. I kept pushing the okay button on the pump which cancels the pairing. So no to a few seconds, more like a few minutes!
Short of re-pairing, I find I can often get the signal back by switching BT off and back on on my phone (IOS). That usually causes it to reconnect at the next data-send from the transmitter (every 5 minutes).
Insulet and Dexcom gave me the same advice. Turn BT on and off, reboot the iphone, and step outside (stepping outside was new advice). This will suck in the winter time. I have also found that Turning the PDM on and off helps. I was wishing the slogan “simply life” would be applicable to me but I am finding the AIDS system quite a lot of work.
Ipone 11 and Tandem X2 CIQ
No problems since last Tandem update or maybe a phone update.
I don’t have many connectivity issues, but that’s because I’ve had to change how I go about sensor and Omnipod placement. Before I got Omnipod 5, I Looped and connectivity was great. I could move my Dexcom & Pod in whatever order I wanted.
Now with O5, I have to be very careful with placement. Opposite sides of the body are guaranteed to be spotty at very best.
So yes, I don’t really have connectivity issues, but I’m also now more limited in where I can place pods depending on where my CGM is.
Up until yesterday it was rarely a problem, BUT yesterday I was ready to trash every single piece! I replaced my G6 sensor an hour before it was to expire. Within the first 10 minutes of the warmup period the t:connect app on my phone (Samsung A51) lost connection with Dexcom. My phone showed that it was still connected, so I closed the app. Then my pump sent an alert that the transmitter ID was invalid. I checked the transmitter box (yes, I’ve learned to keep them while in use) and the ID was correct. I turned the phone app back on and it appeared that all was okay. Then I got another alert from my pump that it lost connection again. I keep everything, pump & CGM, on the same side of my body…so I called Dexcom tech. While waiting on hold, both the pump and phone miraculously connected and the transmitted ID was no longer invalid. I didn’t want a repeat performance, so I waited another moment and spoke with Dexcom tech. As soon as he heard “Tandem” it was no longer a Dexcom problem and I was told to call Tandem tech. I didn’t.
Omnipod 5 PDM has constant issues staying connected to the pod via Bluetooth, thus the CGM. This is a big disappointment with Omnipod 5.
No idea what could be expected “normal” Bluetooth concerns. Only had the Medtronic app a short time, no problems. With just the libre app had a disconnection or two, recently downloaded the “juggluco” in hopes to use with my fitbit. A few more disconnections and once rebooted the phone and it connected.
My daughter recently connected my G6 reciever with my wifes, hers, her husbands, my sons, Cel phones… So they all drove me NUTS every time an alarm went off !!! I got the G6 2 years ago at age 89, T1D 69, and did something stupid that my Wife had to call 911 [ first time ever ] …..
I find that the Dexcom G6 sensors do NOT last or work well the full 10 days. The sensors (I find) start having issues on day 5 or 6. It is very disruptive and annoying. When the transmitter is getting close to its expiration point everything gets chaotic!
Bluetooth? I just use Dexcom 6 and multiple daily injections, but have some receptivity problems with FM radio when cgm is plugged into same electrical circuit. Does this qualify as a Bluetooth problem? Like Elysse I know I’m approaching last day of sensor when readings fluctuate wildly.
They work however I would not characterize them as reliable. Sometime they don’t work and I have a very hard time finding and resolving the issue.
I marked that diruptive bluetooth caused me to disconnect device. This is only true of my pump, my CGM has been fairly consistent with bluetooth.
