because SPI interface is emulated from GPIO interface, if the standby and wake up process is not critical for time needs, you can change the mode to normal GPIO , then set to the states you want. like pin_mosi is defien with WICED_GPIO_21 in WICED_SPI_1.
and you can have a test on SPI_0 and SPI1 also .
SPI0 is multiplexed with GPIO0s and can therefore support a bit banging based software SPI driver.
SPI1 is not multiplexed with GPIO0 and can not support a bit banging based software SPI driver.
So SPI0 is suggested for this thread requests.
