Just downloaded it; nice app that lets you write all kind of NFC commands. Unfortunately, it's still limited in the same way as the other NFC writing apps; so you cannot write tags to turn on/off settings - you can open up the relevant setting, but have to toggle it manually. I was hoping that an official Nokia app would enable this type of automation.
Can you write an NFC tag so that when you scan it it connects to a given bluetooth device ? It would be really handy for my two Logitech bluetooth speaker adapters.
