Would like to know whether anybody used QN908x Controller as a FIDO2 USB/BLE MCU. Kindly let me know if there is any limitation with respect to the FIDO Use case implementation perspective.
Which would be the requirements needed in your device ? Most of the implementations I saw requires an mobile phone to register it, so could you please help me with more details on your application or what would you need the QN9080 to do so I can provide the requested information ?
We would like to design FIDO/FIDO2 USB Token using the QN908x controller, here FIDO token registration takes place using USB interface, so HID USB interface is a necessary to be implemented. We also would like to use BLE interface of QN908x controller for FIDO/FIDO2 authorization So kindly suggest your view on using this controller.
Regards and Thanks,
The device supports both protocols, there is even an example for USB and one for the Bluetooth Le functionality. It will depend on how much memory you will need with the devices as the Bluetooth LE protocol implementation that we have available needs space and the footprint depend on the example you use. You can check more about the footprint in the release notes in the documentation folder of the SDK that you can download form this link.
Also, please take into account that we do have those examples in separate file but there is an effort you need to do when combining both examples in one, as well as you will need to create your custom profile for the Bluetooth LE communication based in the FIDO alliance specification.
thank you for the update. will take a look into combining USB + BLE Example project first, then based on the outcome will move forward with FIDO implementation.
