| − | In the js side, there is a method called <code>window.nx.sendMessage(arg)</code> that sends data to the native side, this method returns a boolean indicating if sending was succesful and accepts a string as an argument. The string is encoded like a C null terminated string in the message content. For receive messages from native part, there is a dom event called <code>message</code> which is dispatched when a message arrives. The event can be listened using <code>window.nx.addEventListener("message", callback)</code> being callback a function which first parameter is like a dom event arg and contains a member called <code>data</code> which contains the string decoded from the arrived message

| − | If messages aren't acked by the native part, js side will not longer receive messages. Ack to web applet '''must''' have 4 bytes after the message content or will crash.
