Bluetooth connection problem since Android 15 update

[Olivier VIENNET]

Hello,

Recently, and probably since an Android update on my smartphone, none of my three Shearwater computers (Perdix AI, Petrel 3, and Nerd 2) are "seen" by my smartphone in the "available devices" (see screenshot).

However, Shearwater Cloud sees them (while the smartphone doesn't.)

But I can no longer connect it to Subsurface.

The Shearwater computers have no problem since I can connect them to another smartphone (Samsung ZFlip running Android 14 and One UI 6.1) and to my computer via Bluetooth.

Subsurface is in the latest version but the problem does not come from it since it is the smartphone which does not see the Shearwater computers

Regarding the versions: 

- The smartphone causing the problem is a Samsung Galaxy S21 running Android version 15 with One UI 7.0

 - My Perdix AI, for example, is running firmware 101/BT10 and its serial number is 30591F7F I've obviously tried everything regarding reboots, connection order, etc. 

Do you have any idea what could be causing this issue with this Android version? 

Thanks.

Olivier
