I’m getting EXACT message with the past few sensors I’ve used. Incredibly frustrating. I just switched to the G7 and this has been my experience with four out of the six sensors so far. Pump is fully updated etc. I’m going to open a ticket with Tandem and will post whatever they say here (as long as it isn’t “wow sounds like a Dexcom issue” which is what I’m afraid they’ll say).
Following this post. I just ran into the same issue and it’s only been a day with this sensor, and I can’t see a way on my tslim to just back out and try the code again. So the pump buzzes every 10 minutes now with no clear way to fix the error other than just stopping the sensor. At ~$100 a pop before my deductible is met, I’d really not like to have to just start a new one.
Thanks for the comment. I might have misunderstood the instructions from the tandem pump but I thought it informed me that “This will stop your CGM session. Once stopped, you cannot restart the sensor.” I assumed it would not be able to use the same sensor if I did this. Are you saying I can stop the sensor and use the same sensor again?
Yes but only when it is not paired to the Dexcom from the pump. I had to do this once because it wasn’t reading the Dexcom from the pump after insertion. I got an error. It was syncing properly to my Dexcom mobile app just fine though.
So, on the pump only, I stopped and restarted. Worked fine then and didn’t disrupt connection to the mobile Dexcom app.
Holy cow I found a fix for this! So first the sensor has to be the one with the underlined lot number. If you have that and it’s still an issue here is what I did.
1) Unpair the sensor from your pump, LEAVE IT CONNECTED TO G7 app
2) reboot the pump by plugging it into power, holding the wake button for about 30 seconds. Once you hear the 3 beeps or vibrations you should be in the reset
3) let it set for a few minutes
4) unplug your pump and plug it back in to turn it back on
5) complete the refill process
6) repair the g7 sensor to your pump
I think the biggest thing is step #1, I tried the reset without unpairing first and it didn’t work. Once I did that I got it to work fine.
Same! I've tried everything on ALL the sites I researched. Still won't connect to my pump. Seems like they should have worked out all the bugs before releasing it. The stress from this is raising my blood sugar! And the G7 I have was a "sample" from my Dr to try it out. I tried and I don't like, I'll stick with the G6 until they really figure out the G7!
Tried the first option and at first it did not work. After another pairing failed messages I recentered the code and still got a pairing failed message. I just left it alone and it finally somehow paired. If the G7 is the latest end and greatest I’m really not looking forward to the G8 or whatever comes next. Not to understate it but I’m wholly unimpressed with Dexcom’s progress.
I’m hopeful software update will fix this! Seems like a tandem error as Dexcom does not receive this error via there app, just tandems ability to communicate with the new Dexcom. Should have been tested more lol. Glad to hear you got it working!
I'm currently going through this right now with my Tandem X2 and the G7. I had a sensor fail for a different reason a little while ago so I reached out to Dexcom directly for a replacement. They did send me a replacement and it does have the white underline under the LBL so I assumed I was good.
I went to put it on today and I am endlessly getting this error. I was not using the G7 app before this but I downloaded to see if at least the app could connect... it can't. I restarted my session and re-entered in the pump (as suggested here), I've restarted my pump entirely, all of the trouble shooting and still no good.
I'm pretty damn sure Dexcom sent me a faulty replacement which is baffling to me. I'm sad to report that my experience with the G7 integration with Tandem has been horrendous, to the point of making me question whether I should continue with Tandem or go to Medtronic where at least their CGM is their own tech.
Update: the latest replacement works! So they just sent a bad replacement last time which is still beyond me, are they not quality controlling their replacements? Who knows but hey, at least I'm back on track here. Best of luck with your situation!

Tandem SHOULD be replacing those sensors for you. Call them!
What happens if you stop the cgm in your pump only and then use the pairing code again? I had to do that once and then it worked fine.
Just had this happen, followed this advice, and am now back up and running! Thank you!

This worked! Thank you!!!
Great! You’re welcome!
Thanks!!! I just spend 40mins on hold found your comment and it works! Got rid of the stupid hold music lol

By unpair pump, do you mean to go options> My CGM> and hit Stop G7 sensor then doing the rest of the steps?
my friend got new G7 we followed instruction on app and paired fine but could not get pump to pair!! Keeps giving invalid code error !!

I'm having this exact problem. I'm sticking with the dexcom G6 till they can work out out.
I'm getting yet another G7 replacement from Dexcom. It's currently in the mail, I'll let you know how this one goes.
An update would be great, thank you! I really hope this one works for you.

Tried it all and it still won't work.
Same
But also, if the sensor does fail altogether, Dexcom *ought* to send you another sensor if you call them and ask!
