Review Windows 10 Mobile configuration settings to determine if the mobile device is enforcing the policy to prevent Bluetooth Low Energy (LE) apps from doing any Bluetooth advertising. This validation procedure is performed only on the MDM administration console. Check whether the appropriate setting is configured on the MDM. Administration Console: 1. Ask the MDM administrator to show the Bluetooth device advertising" security policy. 2. Verify the "allow Bluetooth device advertising" security policy was set to disallowed for Windows 10 Mobile devices. If the MDM does not disable the policy for "allow Bluetooth device advertising", this is a finding.
