''I am not entirely sure whether I have configured it correctly and if it is actually sending the data''

An Oscilloscope would be the tool to verify that...

Ok, we have four posts from over 9 months ago. Please consider stating your own situation, and context. Ideally with some analysis of things with a scope.

Look, the forum doesn't ping old posters unless they explicitly set the post/thread to signal, so floating hopeful queries is not going to work.

State what YOU have done. How you have boards connected, what you have tested and observed, and what exactly is and is not working. Look at the signals with a scope. There have been examples in the peripheral library to link SPI devices (SPI1/2, board to board), look at those and the instructions in the README files related to them. With SPI Master-Slave arrangements there is a one-to-one pin arrangement, RX/TX pins are not swapped around, so MOSI (MASTER SIDE) connects to MOSI (SLAVE SIDE)
