The networking of kha is only js/node target? Any plans to support other targets as Windows/Android?

Sure, once it's finished I'll add it to the native targets. The node target is only for the server component by the way this will be able to work with all targets which implement networking.

Interesting! I am currently working with a microcontroller and a gyroscope and accelerometer sensor, I was thinking of connecting to armory3d, the network of kha actually support TCP / IP protocol?

If not, is there any library I could use in haxe for this? (which supports krom/js target or maybe cpp)

Kha's networking is an automated multiplayer client/server thing which is designed to run on websockets for html5 and plain udp sockets in native targets (which gives better performance for game-like things) - but it doesn't sound like that's what you want at all.
Do you use http or just plain tcp? http functionality is part of Haxe's standard lib, for plain tcp maybe have a look at tink_tcp.

Thx for support @Robert , I'm using http for now, with internal haxe lib, works well.
I'm tweeted my first steps(https://twitter.com/torugok/status/1005495218341400576?s=19)
I will continue to work and bring something new in this direction to kha/Armory3D, thx for this ecosystem!
