WLAN functional description

The Size 4 WLAN module is designed for use with a single antenna shared between itself and a co-located
BT device. The WLAN SW is downloaded from the host engine when the WLAN is turned on over the dedicated
SPI interface. The BT and WLAN engines use common reference clock coming from a dedicated TCVCXO(G8380).

WLAN settings for Phoenix

Use the following to test WLAN using Phoenix:
1 Set phone into Local Mode .
2 From the File menu, select Scan Product and check that the correct product version is displayed
3 From the Testing menu, select Self Test. This opens up a Self Testsdialog, as shown below.
Select the ST_WLAN_TEST check box as shown and then press the Start button. The test turns the WLAN on ,
sets up the SPI interface and then downloads the WLAN firmware into the WLAN module. During the download
the WLAN acknowledges the data blocks and so the self test is a good way to confirm that the WLAN module
is communicating with the Host. The result column changes to Passed after a few seconds if it is operating
properly.
