Determine if the AO has approved the use of Bluetooth at the site.

If the AO has not approved the use of Bluetooth, verify Bluetooth has been disabled:

On the EMM console, do the following:
1. Open "User restrictions on parent" section.
2. Verify that "Disallow Bluetooth" is toggled to "On".

On the Android 11 device, do the following:
1. Go to Settings >> Connected Devices >> Connection Preferences >> Bluetooth.
2. Ensure that it is set to "Off" and cannot be toggled to "On".

If the AO has approved the use of Bluetooth, on the Zebra Android 11 device do the following:
1. Go to Settings >> Connected Devices.
2. Verify only approved Bluetooth connected devices using approved profiles are listed.

If the AO has not approved the use of Bluetooth, and Bluetooth use is not disabled via an EMM-managed device policy, this is a finding.

If the AO has approved the use of Bluetooth, and Bluetooth devices using unauthorized Bluetooth profiles are listed on the device under "Connected devices", this is a finding.
