The RN-XVee module by Roving Networks provides drop-in, certified Wi-Fi connectivity for existing systems using 802.15.4 modules.
The pin compatible footprint and simple ASCII configuration interface allow designers to quickly have the RN-XVee module up and running in existing 802.15.4-based products.
The RN-XVee supports infrastructure networking for worldwide Internet access directly by every node and ad hoc connectivity for fully connected point-to-point networks, unlike many 802.15.4 implementations that need extensive, custom network application profiles and additional bridging products. The module supports industrial temperature ranges, making it suitable for applications such as sensor networks, industrial or commercial controllers, utility meters and M2M applications.
The module is built upon Roving’s RN-171 low-power 802.11 b/g technology, which boasts a complete onboard TCP/IP stack with a simple UART or SPI slave HW interface. The stack offers network services including IPV4 addressing with full WEP/WPS/WPA2 security, HTTP client, UDP, TCP, HTTP TELNET, DNS, FTP and DHCP Wi-Fi protected setup (WPS) amongst others.
In sleep mode, the module consumes as little as 4 μA but can wake, associate and send a full network packet in less than 100 ms. In the connected state the module consumes only 35 mA and its configurable output power allows for optimised TX power consumption. The RN-XVee pins can be configured for digital GPIO or analog inputs. The analog inputs provide 14-bit A to D converter resolution while the I/O can be configured to signal a host microcontroller in order to simplify the interface between the Wi-Fi module and host controller and further reduce system wake times.
