B4J Question Windows iOT on RPi2/3

Dear Guys,

Recently i got hold of a RPI2 with Windows 10 iOT loaded. Just wonder can i juse B4J to create a windows services like application. My application will be using the followings:

• GPIO for pulse countering
• SQLite for DB storage on the external SD mounted
• COM port for RS232 and RS485 for external sensor communications

How about using Andriod on RPi2 and develop using B4A?

Would like to know which available tools (including the free library available now to support the above requirements) should i use develop for the Windows 10 iOT OS.

Thanks in advance.
