The lru is used by OEMs to control the Wi-Fi portion of the radio during regulatory certification testing.

To use lru invoke lru from the command console. Once invoked successfully, the command prompt will change to lru :>. From there ? can be used to obtain information on available commands and parameters.

The lru will search sysfs during initialization to find the first appropriate device to use. If the lru is unable to determine the appropriate device, it defaults to using wlan0 for Wi-Fi devices.

Note: To specify a Wi-Fi interface other than the default, use the -i <interface> command line option when invoking the tool.

Note: Before starting any testing verify the country code displayed in Reg Domain: is correct. See Setup for details.

Note: The radio will remain in a particular test mode until that test is turned off using the off command. Each test should be stopped using the off command before starting another test.

See Test Descriptions for test details and examples.

When finished, exit lru (x), change the configuration soft link back to the standard production WW file, and reboot.
