MAC_Status_t APP_MAC_mcpsDataIndCb( const MAC_dataInd_t * pDataInd ) don't return received data on Mac_802_15_4 FFD example

[APrun]

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?
