Certification/Qualification for Selling product

Hi all,

I want to sell a device that I have made that uses the nrf51822 and the app inside the chip is derived from the ble_app_uart. It uses two chips that communicate using a proprietary service.

What do I need to market it as an Bluetooth device? Do I need to qualify my proprietary service? Do I have to do the qualification and declaration steps from the SIG?

Or can I simply market it as an bluetooth product since it uses your chips?

Thank you for the help, Jorge Costa
