The short version

What changed, and why it matters

This commit adds a user-facing Bluetooth on/off toggle in the device menu for the Trezor Safe 7 (T3W1). It stores the user's preference and only starts Bluetooth at boot if it was previously enabled. There is no direct evidence of a security vulnerability in the change, but it touches Bluetooth state management and storage, which are security-relevant areas.

Recommended action

Review as normal feature code. Verify that disabling Bluetooth actually prevents the radio from advertising/connecting and that the storage flag cannot be manipulated to bypass pairing authorization. No immediate security action required based solely on this diff.

Security signals we found

01

New Bluetooth state persisted to device storage

02

Bluetooth radio startup made conditional on stored preference

03

UI flow added to enable Bluetooth on demand before pairing

04

No input validation, buffer handling, or cryptographic code changed

05

No vendor disclosure of security relevance in commit or changelog
