iX3M2 Import error: Timeout

[rade...@gmail.com]

Hi,

 
I'm using Subsurface with Ratio iX3M2. The sync with DC was working normally on both my devices, Android phone and tablet. About a month ago, I noticed the phone version v6.0.5597.0 is not able to sync the dives anymore with the dive computer. At the same moment, the tablet where I have an older version 6.0.5436, still works normally.
On the phone, after pressing the download button, it throws the "Import error: Timeout". Unfortunately, no further info is visible in the app log.

Anyone else experiencing the same? Any advice?

Thank you,
Radek

The problem is that enabling BLE notifications (which is required for receiving
the BLE data packets) failed:

Many thanks Jef for identifying this issue. I'll be patient and wait if it will be resolved in the upcoming releases.

Just for my understanding, is it related to the new Subsurface version (it works on older one) or the phone/Android version I'm using?
