No data from API

[Ldalvik]

Not sure if something changed or something is up with my Dexcom Follow, but i am no longer receiving data. I get "None" everytime.

Hi, I just ran a test with my account in the US and everything seemed to work.
Could you please share your region, and any debug logging? Any exceptions thrown?

[Ldalvik]

I am in the US region. I will post the HTTP response, but it seems to return 200 but gives me an empty array of data. It's been several months since I used it last, and I had to reactivate Dexcom Follow and get added as a Follower. Is there a period between activating Dexcom Follow and when the API returns data? I cannot think of any reason it wouldn't work besides maybe some setting has changed in the account. As it did seem to work when I used it a while ago.

I tested with another family members dexcom, and it worked. There is no noticeable issues/differences in them, so I am not sure why im not getting data.

It appears that your primary device has logged out and is not transferring data to the cloud.

[gagebenne]

Yep, agree with @dejurin. Give everything mentioned in the quick start a double check. Your password and login seems fine, otherwise you would be throwing exceptions, not getting back None/[].

[Ldalvik]

Thanks, I will give it another try. Both accounts seem to be getting data, as Dexcom Follow shows them live. And I set them up exactly the same. Always weird stuff happening when you're trying to debug lol! You don't even know how long I spent messing with my own library before testing it with this one again, to find out it's unrelated.

[Ldalvik]

hijacking this on an unrelated note, but does anyone know what the root certificate is? I am making a library for an embedded device and currently use insecure access, but had no luck trying it with a certificate.

Hello. I am having the same issue as well in the US with my Dexcom G7. I've tried turning on and off the follow feature and it's now been over 24 hours, but the issue still persists.

Note: I have used this before and it has worked flawlessly until around this month.

Edit: It seems that turning the sharing off and then on and force stopping the Dexcom G7 app can fix the issue.
Seems like there is just a bug where sharing isn't turned on like it is supposed to be; unless I have missed something.

@ar065 So was it just flipping that switch that fixed things? Are you able to see the readings via pydexcom?
