Hi John,
Hope you are doing well. When you download the SDK in the SDK Builder, there are some middleware options to download. Please make sure you add the NTAG I2C Middleware.

After you downloaded the SDK, please import the it in the MCUXpresso, in the following tab. Just drag and drop the SDK zip.

With the SDK you are able to import some examples from the QuickStart Panel, for example the bluetooth_hid_device_freertos and the ntag_i2c_plus_explorer_demo.


When you have both SDK examples, just copy the folder from the NTAG project, to the Bluetooth project.
You will need to add the path of the added folder. Please select the Bluetooth project and go to Properties.

You will need to include the folder. Please click on the Add button, and select the folder from the Workspace.

With this actions, you won't have issues.
If you have any questions please don't hesitate to ask.
Best Regards,
Ricardo
