Connecting SPWF01SA to STM32F469-Discovery

Hi.

 

 

I'm trying to use SPWF01SA for connectivity on my discovery board. I've integrated the parts from the SDK extension and now having issues communicating with the HW. I suspect that my connections are not OK.

 

- I've connected it to usart 6 (+cts&rts signals) (pins 6, 8, 9, 10 according to X-NUCLEO-IDW01M1 - Schematic)

- Reset(3) and boot0(2) (which I assume is the Wifi wakeup)

- I've also connected Vdd (24) and both GND:s (24 and 25).

 

I can see that the reset line toggles OK, and there activity on the uart control signal. However the Wifi chip never ansvers.

 

Do I need to connect any of the other pins? Do I need to connect them? Would it be possible to get any documentation about the integration? I mean the "AN4886 - Wi-Fi module integration design guidelines" in the SAWF01SA page doesn't even have pin out list :O.

 

As separate note is there any documentation how to use that SPI? Would it be possible to get more bandwidth via SPI vs the UART.

 

Thanks in advance!
