Hi,
I use WizFi360-EVB-Mini with STM32 (development board NUCLEO-L4A6ZG) and I am testing the SPI feature of WizFi360. The issue is after I wrote 0x03 to MOSI line, I could not get bit 2 of the response to be high. According to the datasheet I am supposed to get some value back for TX BUFF AVAIL. But I keep getting 0x00.
This is the very first message to send to the dev kit after power up so I am sure there is no data being sent before this. TX BUFF should be available. Also I checked the physical connection multiple times, including ensuring PB13 is connected to ground, and they all look correct.
As a side note, PB13 does not have annotation saying it’s SPI_EN on the dev kit datasheet. Does WizFi360-EVB-Mini support SPI mode at all? If so what else do I need to do to make it work?
Thank you!
