Web Bluetooth API must be disabled.

Discussion

Setting the policy to 3 lets websites ask for access to nearby Bluetooth devices. Setting the policy to 2 denies access to nearby Bluetooth devices.

Leaving the policy unset lets sites ask for access, but users can change this setting.

2 = Do not allow any site to request access to Bluetooth devices via the Web Bluetooth API 3 = Allow sites to ask the user to grant access to a nearby Bluetooth device
