RTOS/CC2650: SPI on SimpleBLEPeripheral does not respond

Part Number: CC2650

Tool/software: TI-RTOS

Hello,

I am trying to run SPI using the basic project SimpleBLEPeripheral for Launchpad CC2650. I should have done everything properly: added the drivers, initialized the SPI parameters (BLOCKING mode), specified the SPI bus pins, open the SPI bus and getting a handler different than NULL. However, when running the spi writing function I can't see any response on the oscilloscope when checking the MOSI pin. I tried to check everything that could make a problem and I am somehow out of ideas what to try more... Any help?
