This couple files don't seem like UI code, so they should go in
chrome/browser/bluetooth instead of chrome/browser/ui/bluetooth.

Done.

A non-boolean function shouldn't be named Has*. This could be
GetDevicePermission() or GetAllowedServices(), depending on whether we need to
expose it to BluetoothDispatcherHost in content/. We probably will need to
expose it, and in that case it needs a signature compatible with other choosers'
data so the result can go through the content::ChooserPermissionManager
interface. So, probably GetDevicePermission(), returning a
base::DictionaryValue.

[juncai, 2016/01/25 18:53:32]

This function is removed since it is not used by other function.

+      const url::Origin& requesting_origin,
+      const url::Origin& embedding_origin,
+      const std::string& device_address);
+
+  void OnGetAdapter(scoped_refptr<device::BluetoothAdapter> adapter);

[Jeffrey Yasskin, 2016/01/21 00:32:30]

I believe this can be private.

[juncai, 2016/01/25 18:53:32]

This function is removed since the permission object is constructed by
BluetoothDispatcherHost.
