Where can I get JN5189 SDK (JN-SW-4470)?

[grafalex]

I am going to purchase a module on JN5189 microcontroller. Surprisingly I have not found an SDK for it, despite there are multiple references to it - JN-SW-4470. I tried googling, as well as searching on the NXP web site - no luck. 

Where I can find the SDK?

Hi,

I also don't find the jn-sw-4470. How do you know it? The JN5189 sdk is all here.
