Inventek Systems offers a family of serial-to-WiFi modules (eS-WiFi™ family) that support Broadcom Corporation’s WICED™ platform. The option is available to use either Inventek’s AT Command Set firmware or Broadcom’s WICED APIs. When using Inventek’s AT Command Set, a low cost system microcomputer is used to send commands to the eS-WiFi module over a serial interface (UART, SPI or USB). When using Broadcom’s WICED platform, the on-board microcomputer is used for both the WICED firmware and system program. In either case, the module hardware is identical and consists of a Broadcom BCM43XX single chip wireless radio, embedded Cortex M3 Microcomputer and integrated antenna (or U.FL option) all on a 14.5mm x 34mm module with 44 LGA footprint or USB dongle.
WICED™ – Wireless Internet Connectivity for Embedded Devices (Broadcom Corporation)
Broadcom’s Wireless Internet Connectivity for Embedded Devices (WICED) platform eases the development effort and simplifies the implementation of Wi-Fi connectivity in an array of consumer devices, especially those with no current networking support.
WICED modules enable the addition of secure, interoperable Wi-Fi functionality via a simple serial port using a basic command set that does not require any significant changes in product micro-controller architectures.
eS-WiFi™ – Embedded Serial-to-WiFi Modules (Inventek Systems)
Inventek’s eS-WiFi modules build upon the WICED platform by adding another step in integration and ease of design-in. These AT Commands allow the use of simple instructions to establish connectivity and configure the module as a client or Access Point. Over 100 commands are now available and include a broad list of basic and advanced commands (Find, Scan, Join, Send, Receive, Run SoftAP, Direct Connect Mode, SSL Mode, etc.).
