Sorry, I'm not sure how I missed the notification for this.

I'm a little surprised by the abnormally short broadcast there. A few questions:

1. Does this happen repeatably, or was it just an issue with a mis-received broadcast one time? (I assume the former, but if it's the latter, that would be good to know.)
2. What firmware version is your Aranet4 device on?
3. Do you have the "Smart Home integration" toggle enabled or disabled in the app?
4. Have you had success with any other Bluetooth integrations with Home Assistant?
5. Do you have a "Sensor display name" set for your device? If so, can you share what it is?

My understanding is that the broadcast is generally fixed-length, and doesn't have optional fields, but if I can reproduce the issue locally I can try to make a PR to the aranet4 package to resolve the issue.

(Also, if you have the ability to easily capture that BLE broadcast, that would certainly be interesting to have as well, but it's a moderately complicated procedure.)
