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!
