Dexcom G6 transmitter and receiver pairing 1 hr and 45 minutes

Hello everyone,
I have Dexcom G6, my transmitter and receiver pairing for 1 hour and 45 minutes already. I call Dexcom Technical Support and staying on hold.

Does anyone have this issue?

Would you please help me?

Thank you,

It should pair right up in 15 minutes or less, usually more like 1-2 minutes. Is your transmitter firmly set into the sensor? If it is, try another sensor. If that does not work, you have a bad transmitter. Document everything you do so they will send you replacement sensor(s). Get to Dexcom ASAP unless you have a spare transmitter as it will take them 7-10 days to get you a new one during a holiday weekend.

This does happen to all of us, from time to time, although rare.

Yes, it seems the transmitter is dead. Stay on hold, Have them replace the transmitter and sensors wasted. In the meantime make sure that are not any connections or devices interfering with it.

Do you also have a phone with Dexcom app? If your receiver is the problem, a phone app may still work.

Or if you have non-supported android phone, you could use xDrip to display data.

I don’t use my phone as it is not supported by Dexcom and have always only used the Dexcom receivers. I have never seen a pairing issue be a receiver issue. Anything is possible, but in my experience of occasional pairing issues it has always been either a sensor or transmitter issue with the G6 as well as previous models.

I have had Dexcom receivers stop working, scrambled brains, stuck buttons, dead batteries, etc. but never a pairing issue be a receiver issue. Has anyone on this forum had a pairing issue be a receiver issue? That would be great to know for future reference.

Since he says his receiver is in pairing mode for 1 3/4 hours, that would mean that the bluetooth icon on the receiver is flashing but not locking onto the transmitter bluetooth signal. If he was not getting a flashing bluetooth icon, then I would think that could indicate a possible receiver issue.

If you’re using android go into your bluetooth and look for any and all Dexcom listings under ‘paired devices’ and unpair them all. After they are all removed start the process of pairing your transmitter again.


Yes. It is not clear to me whether you are attempting to pair the transmitter and display device for the very first time, or if you have done this before and may have devices which may have previously paired with your transmitter.

I’ve done this like 2 years ago. I didn’t use a device because supplies were not covered. Recently I have got a pack of three sensors, I set a transmitter into the sensor and tried to pair transmitter which I used first time I got Dexcom G6 and receiver and pairing process was about 2 hours. So I decided to remove a sensor because I spoke to one of Dexcom representatives and she said that I need a new transmitter.

So you were using a 2 year old transmitter?

Well, you do need a new transmitter every three months but just to add to this, my receiver died a few weeks back. They sent me a new receiver. We were about to send that one back because it took about an hour to pair. And that is very unusual.

Sorry, but I just continue to have nothing but questions about what actually happened here.

Are you sure you aren’t confusing the “pairing process” with the required initial 2 hour calibration the G6 needs to perform after it is started? After the G6 transmitter and the receiver were talking to each other, was there a another delay for the 2 hour calibration? (A total of ~4 hours before the CGM was working?)

Did Dexcom offer to replace the transmitter. I would be surprised if they did since, in the United States at least, I think the transmitter is technically “dead to Dexcom” 5 months after it was shipped to the end user. Depending on the mood (?) of the Dexcom cust rep you talk to, they may or may not replace a faulty out of warranty transmitter. But on paper I think Dexcom can always decline to do so.

My initial G6 shipment included 2 transmitters. I used one transmitter for 100 days and then switched to the second one. I wasn’t receiving any warning messages from my t:slim x2 pump about impending transmitter death, but I decided not to risk it.

I’ve kept that “aged” transmitter to use as a possible last resort if my current transmitter dies. I don’t know if this would work out or not, I just felt better having at least a possible backup rather than trying to push each transmitter unto death. :man_shrugging:

The second transmitter has been used now for a little over 60 days. I now have a script in place for a replacement transmitter which hopefully won’t take longer than 10 to 14 days to be arrive. :crossed_fingers:

While it is most likely a faulty transmitter, I would go through the normal steps when just about anything electronic doesn’t work – try again.

In this case, I would do what many people do when reusing a sensor for another 10 days – carefully remove the transmitter from the sensor holder (I use a test strip, others have used a thin credit card to release the latches on opposite sides of the sensor holder. When reusing a sensor, you need to wait 30 minutes, but in this case, I’d just wait a few minutes, then pop the transmitter back in and start over. While the transmitter is out, I would also shut down the receiver so in effect, you will be rebooting the receiver.

it is worth the try in case it got confused or the transmitter was not making a good connection to the sensor holder. If this small trick fails, though, I agree with all posts that I’d work with Dexcom to get a replacement transmitter and any wasted sensors.
