I am running the Mac_802_15_4 FFD and RFD examples on 2 STM32WB55 Nucleo bords.On Coordinator, the APP_MAC_mcpsDataIndCb function is triggered but don't save the data in the Mac_dataInd_t structure. What can I do to receive data?

I want to enable Terminal I/O using SWO for printf() function. I can't figure out why Iit doesn't work on that examples. It work on other examples (FreeRTOS and HAL Template).I follow the instructions from the IAR EW app manual and it doesn't worked....
