ARM Processor Wireless Connectivity Software specifications

General Description

The product is delivered with a complete software development kit, which includes all required SW components in order to successfully communicate with the wireless connectivity extension card. For the WLAN part, a full-features driver is provided along with its source code and a variety of demo applications. The Bluetooth is integrated with the BlueZ protocol stack in Linux and with Microsoft's stack in WinCE. You may refer to the Getting Started Guide for detailed step-by-step information regarding both WLAN and Bluetooth software.

Linux

WLAN Apps

User level utilities and applications, which communicate with WLAN through the driver (such as: ping, browser, ftp client and so on).

• Data-path interaction is achieved through the network stack (IP stack)
• Management and control is achieved through direct function calls to the WLAN driver API

WLAN Driver

The WLAN driver is a Kernel module which implements the device driver. It transfers data to and from the device and the network stack and it manages and monitors the WLAN connection and all related activities, as required by the WLAN protocol.

WLAN interface with the Host

Hardware interface that is supported is SDIO and SPI, however we do only provide the SDIO driver and it gives the option to the customer to develop his own SPI driver

Linux BlueZ and OpenObex

• BlueZ and OpenOBEX are not TI products. They are managed by the Open Source community and as such are provided as-is
• BlueZ is the official Linux Bluetooth® protocol stack. It is part of the official Linux kernel since version 2.4.6.
• BlueZ is an Open Source project distributed under the GNU General Public License (GPL).
• BlueZ supports a variety of profiles based on implementation from various sources that must be collected and integrated by the OEM/ODM. E.g. OpenOBEX adds profiles for file and object transfer
• For more information about BlueZ, visit the BlueZ website and OpenObex website
