Bluegiga Wi-Fi® Software Stack


The Bluegiga Wi-Fi Software is an embedded 802.11 MAC and IPv4 stack targeted for Bluegiga's WF121 Wi-Fi module. The software implements full 802.11 functionality, WPA2, WPA, WEP, and WPS encryption protocols and various IP-based protocols, such as TCP, UDP, DHCP, DNS, ICMP, and HTTP. The Wi-Fi software also supports the 802.11 access point and HTTP server functionality for the easy configurations and direct connections with phones, tablets, and PCs.

Bluegiga's Wi-Fi software provides powerful, low overhead, and easy-to-use Bluegiga BGAPI™ serial protocol that can be used over UART, USB, or SPI interfaces. BGAPI serial protocol provides access to functions, such as Access Point discovery, association and encryption and connection establishment as well TCP and UDP data trasfer. To simplify the software development for external host processors the Bluegiga Wi-Fi software also includes a Bluegiga BGLIBTM C-library that implements the BGAPITM serial protocol parser and it can be easily ported to various embedded systems.

For standalone applications, the Bluegiga Wi-Fi Software also provides a simple BGScript™ scripting language and VM environment, which enables users to write simple applications for the WF121 Wi-Fi module. This enables lower cost and smaller designs without the need for an external MCU.
