esp32 spi not sendig NULLs

[danny@cs.huji.ac.il]

Hi,
I connected a Saleae Logic analyzer and I can see the MOSI data that I transmit, but
I realized that nulls are not being transmitted!
some commands have 0x00 as data!

Can you give an example of the code that evokes this behaviour? Also, if you suspect this is a bug in esp-idf, we'd rather you report an issue on the esp-idf Githup repo rather than in the forums: Github is slightly better equipped to handle those.
