Wifi Shield V1.1 with SPI through NucleoF401RE

Hi everybody,

I’d like to interface my NucleoF401RE with SeedStudio wifi shield v1.1.
Issue I met is that serial bus used for communication between Nucleo & shield is the same than serial bus used for ST-Link debugger.
And there is only one serial bus through NucleoF401RE MCU.

Through Seedwifi shield mbed developper community, I saw it was possible to address the wifi shield using SPI.

Does anybody has already experience SPI with SeedStudio wifi shield?? I’d like more information concerning how configure the shield in SPI.
Maybe an example code !!??

I can’t understand how the MCU should be configured because only 2 SPI pins seems to be used.
SPI is 4 wires: MISO, MOSI, SCLK, NSS.

Thanks in advance for your answer.

Best regards,
