Hi,
It does not work. I wrote to tech support. I have received following response:
Please check the following precautions when you use the spi pins of XIAO ESP32S3:
Pin Multiplexing | Seeed Studio Wiki
You need to cut the pcba as labeled in figure 1, it’s connections are located inside the pcb.
I did not want to cut anything so I bought eval kit based on ESP32-WROOM-32. The new eval kit communicate with my board via SPI, but I have got wrong data. It does not work correctly. ESP32 is nightmare ( even codes from EDP-IDF do not work). I have to come back to Sierrawireless chips. Sierra processors are not cheap, but works.
Thanks for your help.
