No further readings from G7 on Pixel 7pro

[Nawygator]

Hey there,
I am using a Google Pixel 7 Pro on Android 15 beta, Dexcom G7, xdrip nightly.
It worked until the last Android update. Now, I only get the actual reading (and past values) directly after pairing, but afterwards I only get power connect errors, Auth errors and similar.
Workaround: Right now I change the "dexcom sender id" to a different one and back to the original, delete the BT device and then restart my phone. After 5 min I can Accept the pairing request and get the past values.
I tried changing most of the options for dexcom and bt, but nothing could help me out of this loop.
TIA, im grateful for any tips.

How old is that G7?
Can you check the logs to see how fast Voltage B has been dropping?

It is very interesting and puzzling.
If you look at the image at the bottom of the following linked page, you will see the voltages I have experienced with 14 different devices. They agree with most readings I have also seen reported by others.

Voltage B is after 2,5 Days currently at 215.
It seems to me, I got a bad batch. Every Sensor is produced on the 1st of April 2024.

Sometimes it works for a few hours, sometimes just one reading.
I need to change the sensor id and delete it from Bluetooth, but at least I don't have to restart my phone 15 times a day...
I have been using G6 and G7 since 2016, but the last weeks are the worst

What happens if you use Dexcom app? Does it behave the same way? Or, does it work fine with Dexcom app? That will be a crucial piece of info.

You can just switch xDrip to disabled collector: https://navid200.github.io/xDrip/docs/Stop-xDrip.html
Then, you won't have to uninstall xDrip. Then, install Dexcom app and follow the instruction to connect to the current G7. Does it work?

I'm running into this same issue, not sure if there was a resolution or not, but it's connecting just fine to my Tandem Insulin Pump, not getting connection to my phone at all

Also seeing the following in the log:

Brand new sensor, unable to even get any battery information

I've really been struggling with even getting the Dexcom G7 app to pair with this sensor, I kind of assume this is just a garbage sensor, was able to connect to my insulin pump without issues, but phone has been a nightmare (had pairing issue with PIN, etc. but was finally able to get the G7 app connected

[jamorham]

Move old removed sensors far away as they can interfere which is what the mismatch errors are likely about.

it took 8 hours, and I had to turn on OB1 unbonding at least momentarily, but I was able to get it started finally at 3:00 AM when I was somewhat having insomnia. I think this sensor just has loads of different problems with it, I had it fail with the same scenario during runtime on the G7 app directly too, but it was consistently working on my insulin pump. Still not sure how I feel about this generation of sensors

I've been debugging a similar issue on my end for the past week. This looks like it might be similar, but I can't tell unless someone is able to post a logcat log (ideally) or at the very least logs after enabling this: https://github.com/NightscoutFoundation/xDrip/wiki/Enabling-Debugging-for-OB1-collector
