WiFi mt7697 - le_wifiClient_Start() ERROR



I have a mangOH red with a wp7702, I have followed all instructions here to set up the wifi built in :

I’m actually try to connect the mango to my wifi access point but when starting the wifiClient in my application with the function le_wifiClient_Start() it return an error was “LE_FAULT”.

However i’m able to create an access point with the wifiWebAp application and connect with my phone.

Can you say me if it’s normal because the wifi client driver is not ready yet or is my driver was not correctly install ?
