Upper electro-detection, initialization；
8) after the completion of initializing, according to configuration testing parameter to each of the WiFi module (200) to be measured with SDIO interfaces
A test event is detected；
9) test result returns to the host computer (300) in real time；
10) after the detection of all test events, the test board (100) with Liunx kernels to it is described it is to be measured with
The driving of the WiFi module (200) of SDIO interfaces carries out soft unloading；
11) after the completion of soft unloading, the test board (100) with Liunx kernels closes the power supplys of SDIO interfaces, signal
It closes；
12) WiFi module (200) to be measured with SDIO interfaces is removed；
13) WiFi module (200) to be measured with SDIO interfaces more renewed repeats 5) -12) the step of complete a new round
Test loop.
