Description
The WiFly GSX module is a stand alone, embedded
wireless 802.11 networking module. Because of its
small form factor and extremely low power
consumption, the RN-131G is perfect for mobile
wireless applications such as asset monitoring, GPS
tracking and battery sensors. The WiFly GSX module
incorporates a 2.4GHz radio, processor, TCP/IP stack,
real-time clock, crypto accelerator, power
management and analog sensor interfaces. This
complete solution is preloaded with software to
simplify integration and minimizes development of
your application. In the simplest configuration the
hardware only requires four connections (PWR, TX,
RX, GND) to create a wireless data connection.
Additionally, the sensor interface provides
temperature, audio, motion, acceleration and other
analog data without requiring additional hardware. The
WiFly GSX module is programmed and controlled with
a simple ASCII command language. Once the WiFly
GSX is setup it can scan to find an access point,
associate, authenticate and connect over any WifI
network.
