We are evaluating the S2C module on our reference MCU platform (STM32) for possible use on a new product.
Module is XB24CAPIT-001 (CAPIS version will be used on the product)
Firwmare version is 2001
Hardware version is 2E
Interface is SPI (@2.5MHz) with ATTN on interrupt.
A frame is sent:
0x7E 0x00 0x04 0x08 0x06 0x43 0x48 0x66
ATTN is asserted around 150 us later.
When reading data I always see:
0x7e 0x00 0x02 0x8A 0x00 0x75
The same operation when using UART generates proper AT Command Response.
Is there anything wrong in our setup?
