xperia XZ premium does not log BT sessions

[Bisak]

Hello,

I have some problem with BLE device. I have activated BT HCI logging in Developer menu as well as USB debugging, reactivated BT but log file is not stored anywhere, internal nor external storage. How can I configure xz premium to store this log?

My phone is updated to the latest OS release.

Thank you, Martin

I have found the file as a part of troubleshooting report. So it cannot be downloaded separately.
