Yup, and I couldn’t make it work. The problem is here:
As soon as you do the “forget” thing, you don’t get any sensor options, just the “Can’t connect to transmitter” message.

Think it’s a software issue with the iPhone? Apple has screwed up a few things with their last update 12.4
With zero hands-on experience with this, I can’t offer any further analysis except that additional interaction with Katie at the Facebook Looped group could help troubleshoot.

@Terry4 do you think this has anything to do with upcoming rollout of the G6 to Medicare patients?
No, I don’t. Besides, if Dexcom can reliably produce accurate data for the 14 days of the upcoming G6+ model then I don’t think restarts will be attractive to most users.
The 14 days sounds about the right amount of time for each sensor session. I hope they get going with the rollout for all the Medicare patients.
I think it’s more of a regulatory than a technical issue. I seem to recall that they wanted it certified for 14 days when they first rolled out, but didn’t get it. And I regularly get 20 days of good data out of 'em, no problem.
One of the reasons for wanting to extend past the statutory limit is that it means after a while I end up with an extra sensor or two in case of failures, which can happen for all kinds of reasons (e.g, accidental yank-outs, bad/painful insertions). Fortunately they’re pretty good about sending replacements without a lot of fuss, but it can still take a couple of days. It’s not the end of the world to go CGM-less for that amount of time, but it sure feels like someone’s yanked a prop out from under you. There have been several times I’ve been glad to have an extra sensor on hand to avoid that. And that won’t change when they go to 14 days.

It’s not a money issue with me either. But I started restarting them because I wanted a back up supply like I had with my Libre. Being without one when you are used to it drives you a little nuts.
Plus the ones that stay on work better, it just 1 or sometimes 2 calibrations and you are usually good to go. The new ones vary more.
AND, it’s just a hassle of one more thing to change out that I’d prefer not to.

Of course. I’m a big fan of spares and the luxury they bestow for the “just in time” inventory system preferred by the payors who don’t have to live with their own policies.

I can live without restart. I had my endo write my script for 4 boxes over 90 days - 3 extra sensors. Not being able to presoak is a bigger issue for me. Without it I’ll be dealing with worthless numbers for the first 12-24 hours.

Why can’t you soak a G6 just like I soak a G5?
Supposedly, when you attach the transmitter it detects the insertion. If it’s too smooth the new transmitter won’t start the sensor session. Soaking would cause a smooth transition from the transmitter being attached and sensor startup.

So I wonder if we can fool it by eating some pure sugar in the warm up period to get it to spike while taking some insulin before to combat and drop it down within 15 minutes?
That doesn’t get past the insertion detection though…
I wish my sensor would last even 10 days. So far only a couple have, and they started having jumpy readings one.or two days earlier, the others just had sensor errors.
Speaking of, my transmitter will be expiring in a few days. If I reset it, won’t Dexcom know I did, and then not provide customer support for all of the ongoing failed sensors? I had a sensor error today, and Dexcom said they would not provide any support if the transmitter is older than 90 days. My transmitter actually is still working, but the sensor failed! Still they wouldn’t replace it!
Sorry for sidetracking your thread @DrBB but it is a related issue

So how does anyone do restarts if the xmitter looks for smooth data and won’t start if it detects that?
You folks DO realize you are making me glad I’m still on a G5, right?

That’s the million dollar question. This is all Dexcom trying to thwart the 3rd party hackers.
Start session, end session. Rinse and repeat for weeks at a time. Couldn’t beat that simplicity

Thanks for reminding me that I need to read about how to do this. I have to rebuild anyway. I’m trying to lay this out in a summarized way. If I made a mistake, please message me directly and I’ll change it. If you have tried a method and verified it was or was NOT effective, I’ll make a note of that next to your name.

G6 80XXXX Transmitters
The following 4 methods have been successfully VERIFIED by Tu 80XXXX Users…
Reset Documentation:
Method 1.) XDrip+ trick “Enable Engineering Mode”/“Hard Reset Transmitter” Method.
Method 2.) Saving the tab that has the code number and UID code on it. I start a new session with no code, wait 15 minutes, then stop and start a new session, and enter the code via a new picture from my iPhone.
Method 3.) Faraday bag method - Using the restart method from SeeMyCGM – turn on the receiver, do new sensor on the receiver, put it in a Faraday bag for two hours, take it out and wait a few minutes. See Option 1 at this Link.
Method 4.) Spike Configuration. Spike Link. FB Spike Group Link. Its believed that NightScout must be installed prior to Spike in order to perform restarts.

Fred_E transmitter battery replacement notes:
Replacing the battery does NOT reset the transmitter… Here are simple instructions for using XDrip+ to reset the transmitter to 0 Days…
In XDrip+ Android do the following right before you “Stop Sensor” in preparation for replacing the sensor and getting rid of the transmitter with the dead battery:
a) Hit the little Eyedropper icon on the right side of the XDrip+ main screen… This will take you to the “units” screen. Hit the little Microphone icon on the “units” screen and follow the prompts and speak the words “ENABLE ENGINEERING MODE” into your phone’s microphone. Sometimes it’ll misinterpret what you’ve said and it’ll think that you said “and able engineering mode” or something. Keep repeating these instructions till it understands you and says “Engineering Mode Enabled – Be Careful!” on the bottom of the XDrip+ main screen.
b) Once you’re in Engineering Mode, do the same thing as you did in step a), except say “HARD RESET TRANSMITTER”…
c) Then, go to the “System Status” XDrip+ screen and wait up till 15 minutes for the “Transmitter Days” to reset to 0…
d) If the “Transmitter Days” doesn’t reset to 0 in a maximum of 20 minutes, repeat the previous steps…
NOTES
mohe001 tried Terry4’s No Reciever Restart Method and found that Dexcom app threw a “Transmitter not found” error message after performing the, “Forget/delete Dexcom from Bluetooth list in phone’s settings.” Option to Stop Sensor was available, No option for “New Sensor”, enter code, “Start Sensor.” Since the phone was no longer communicating via BT with the transmitter, everything went bad until I inserted a new sensor and the phone was able to locate it. Loop v1.10.0DEV
The next, new sensor was started conventionally and failed (suspected software related failure) within 2 days. Dexcom app/Tidepool showed sensor age to be _______.

@Jimi63, if you come across the article will you post it? I’ve been on a G4 until last month, so I am super out of the loop.
