RN-340M-W

RN-340M-W is a WiFi serial adapter that supports RS232 interface and with male DB9 connector. When connected to a remote host it transfers data, read or written, to the serial interface of a remote application such as an iPhone app, data logger or PC control console. Data is transferred over a reliable TCP/IP socket or by using other protocols such as UDP and HTTP. 802.11 b/g infrastructure or ad hoc networking has the advantage of using existing low cost wireless connectivity and is able to remotely connect to any WiFi serial adapter in the world. The RN-340M-W has a wire antenna. A built in HTTP client can be used to post data to a remote server without the need for any host controller. By simply enabling the HTTP protocol, the RN-340M can wake up and send data to a remote server as an HTML post. This feature allows the RN-340M to be an off the shelf, standalone networking client that does not require any software programming.
