Chapter 198. Configuration
Table of Contents
This chapter shows how to include the WLAN support into an eCos configuration, and to configure it once installed.
198.1. Configuration Overview
The common eCos WLAN layer is contained in the
package CYGPKG_NET_WLAN. However, it depends on the
services of a collection of other packages for complete
functionality. Currently the WLAN implementation is tightly bound with
the lwIP TCP/IP networking stack provided by
the CYGPKG_NET_LWIP package.
Incorporating the WLAN support into your application is
straightforward. The essential starting point is to incorporate the
WLAN eCos package (CYGPKG_NET_WLAN) into your
configuration.
This may be achieved directly using ecosconfig add on the command line, or the Build->Packages… menu item within the eCos Configuration Tool.
198.2. Configuration Options
Once added to the eCos configuration, the WLAN package has a number of configuration options.
The CDL configuration provides default settings for the use by wireless network interfaces. The application documented in Section 200.2, “wlan_switch” provides an example implementation of using the run-time interface configuration, where appropriate, to associate with different access-points.
-
CYGDAT_NET_WLAN_COUNTRY - This option is used to define the regulatory domain for the radio.
-
CYGPKG_NET_WLAN_STAx If infrastructure (station) interfaces are provided by the underlying wireless device driver package then a number of these STA
xoptions become available.-
CYGPKG_NET_WLAN_STAx_SSID - This option specifies the SSID (network name) that the interface should associate with.
-
CYGPKG_NET_WLAN_STAx_SEC - This option is used to select the security encoding required to associate with the named SSID access-point.
-
CYGPKG_NET_WLAN_STAx_PASS - For pre-shared key security encodings this option supplies the passphrase associated with the SSID access-point.
-
-
CYGPKG_NET_WLAN_APx If master (access-point) or adhoc (p2p) capable interfaces are provided by the underlying wireless device driver package then a number of these AP
xoptions become available.-
CYGPKG_NET_WLAN_APx_SSID - For access-point or P2P interfaces this option supplies the network name used for the connection.
-
CYGPKG_NET_WLAN_APx_SEC - This option specifies the security encoding exposed by the interface.
-
CYGPKG_NET_WLAN_APx_PASS - For pre-shared key security encoding this option defines the passphrase to be used.
-
CYGPKG_NET_WLAN_APx_TYPE - This option allows selection between the “Infrastructure”(master, access-point) and “Adhoc” (P2P) interface modes.
-
CYGPKG_NET_WLAN_APx_CHANNEL - The radio channel to be used for the interface.
