WLAN selftest and coexistence test in Phoenix

Prerequisites

Connect complete phone assembly to a PC with Phoenix service software using a USB data cable.

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 Test dialogue box, as shown below.

Select the ST_WLAN_TEST check box as shown and then select Start button. The test turns on the WLAN, 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 will change to Passed after a few seconds if operating

properly.
