For cellular applications, the Wireless Development Kit also supports Siemens’ MC55 range of
GSM/GPRS modules, which are pin compatible with EZURiO’s wireless LAN module. This permits
designers to develop products which can support either short range or wide area wireless
connectivity, with incredibly fast time to market.
17. Interchangeable 802.11 Module
EZURiO’s range of Wireless LAN modules have been designed to be
physically interchangeable with the BTM402 Bluetooth module and
the BISM Bluetooth Serial Module. For product designers this
means that they can design a single pcb, which can be populated
with either an 802.11 or Bluetooth module, giving the opportunity to
launch two different variants of wireless connectivity at minimal
additional engineering effort.
The WISMC01 802.11b/g TCP/IP Wireless LAN Module is a fully
integrated and qualified wireless device server, designed to make it
simple to embed 802.11 connectivity.
Unlike other wireless modules all of the necessary drivers, protocol stack, security algorithms and
antenna are integrated. The module also includes an interpreter that can run scripts, providing a
complete wireless processing solution. It enables you to add wireless internet connectivity to almost
any device with a serial port. The module is designed for lowest cost of integration and ownership. It
is ideal for enabling M2M applications.
The module is a dual processor design, dedicating one processor to the 802.11b/g baseband with a
second powerful ARM7 processor, with 16MB of SRAM and 64MB of flash memory running the wireless
drivers, TCP/IP stack, web server and UWScript interpreter. Connection to the host device is via a
high speed 921,600 bps UART, with an additional twelve GPIO lines and two 10 bit ADCs. The
interpreter allows complex scripts to be run, allowing the WISM module to operate with zero host
loading. It means it is possible to use the module to wirelessly enable “dumb” sensors or UART ports.
