All right! I have another question though, regarding certification.

If I use nRF8001 and design the rest of the chip I'll need a certification to use it for commercial porpuses right? What if I use a module like this one: learn.adafruit.com/.../introduction

Will I need a certification as well?

The nRF8001 can only act as a Peripheral device, so it will not be suitable for your central unit. You can however, like you ask, use a nRF51822 on your central unit and a nRF8001 on the remote. The nRF51822 acts as a Central device with the S120 SoftDevice programmed.

With 2 nRF8001 would I be able to connect the central unit of my system (an ARM MCU operating a bunch of sensors and relays) to the remote controller (TFT+MCU)? Or do I need a nRF51822 on my central unit and a nRF8001 on the remote?

The simplest method to add wireless to a design would be to use the nRF8001, this is the easiest to use and integrate. nRF8001 is a peripheral only device so it connects to Phones, laptop, tablets and other master devices. If you require more flexibility (peripheral and central) you can use the nRF51822 or if possible run your entire design on the nRF51822 as this is ARM based.
