I connect the wizfi250 through USB cable and send the following command through putty : AT+MSP1=2,0 in order to set as communication interface the SPI, I get a response = “OK”
Then if I query the wizfi again with AT+MSP1=?, then I get " AT+MSP1=1,0"
Why the mode changed from “1” to “2” ? Will I be able to use SPI?
Is there an instruction set or datasheet regarding SPI driving of wizfi 250?
Thank you ,
