The Battery powered WiFly serial Adapter supports RS-232 interface. When connected to a remote host, the WiFly serial adapter transfers data read or written to the serial interface to a remote application such as an iPhone app, data logger or PC control console.
Data is transferred over a reliable TCP/IP socket or using other protocols such as UDP and HTTP. 802.11 b/g infrastructure or adhoc networking has the advantage of using existing low cost wireless connectivity and being able to remotely connect to any WiFly serial adapter in the world.

HTTP Client
The WiFly has a built in HTTP client that can be used to post data to a remote web server without requiring any host controller. By simply enabling the HTTP protocol, the WiFly can wake up and send data to a web server as an HTML post.
This feature allows the WiFly serial adapter to be an off the shelf, standalone networking client that does not require any software programming.

Perfect iPhone Application
The WiFly serial adapter can easily connect to an iPhone/iTouch. It is a simple non-restricted solution to connect your external device with an iPhone app. Simply setting the device in adhoc mode allows any Wi-Fi enabled computer or smartphone to control and monitor serial devices. In this mode, the WiFly broadcasts an open network that the iPhone/iTouch can connect to. Once the connection is established, data can be transferred between the WiFly and the iPhone/iTouch app.
