Can't communicate through SPI port on F9P


I’m used to using the UART1 port to read and write data on the f9p from a Raspberry pi 3 but there is a thing…

Recently I decided to used the SPI port but I can’t get any data from the F9P, I enabled on U-center SPI port and some msg (nav-pvt, nav-status) on SPI port as well but nothing appears on the Raspberry when I try to communicate with the f9p.

That’s curious because SPI works fine with another product of yours, the RM3100. I used same wires, same SPI bus and same SPI library.

Maybe I missed something on the f9p configuration ?
I take all the advices you can offer me.

Thanks in advance.
