Description
The WiFly GX module is a stand alone, embedded
wireless LAN/WAN access device. Because of its
small form factor and extremely low power
consumption, the RN-121G is perfect for mobile
wireless applications such as asset monitoring, GPS
tracking and portable devices. The WiFly GX
simplifies the integration and development of your
application by including an on board TCP/IP stack and
networking application programs such as telnet and
ftp. The hardware requires only four connections
(PWR, TX, RX, GND) to create a simple wireless data
connection. Additionally, continuously sampled analog
inputs transmit audio, temperature, motion, or
acceleration data without requiring additional hardware
in your end application. The WiFly GX module uses a
straight forward ASCII command set for configuration
and programming. Once the WiFly GX is set up it can
automatically associated and authenticate with a
network, making your device accessible worldwide.
The WiFly GX includes a high-speed UART and SPI
interfaces that allow high-speed data transfer. The
WiFly GX module is a complete wireless solution
