I'm writing an App that need tcp and upd interface, I used this https://github.com/MobileChromeApps/cordova-plugin-chrome-apps-sockets-tcp and this https://github.com/MobileChromeApps/cordova-plugin-chrome-apps-sockets-upd
I've already tried the upd plugin that works right, I suppose that also the tcp works (I haven't completed the tests for now).
