For the First question, on a BLE app, you can enable FREERTOS on the middleware throw CuebMX:
But you can't use FREERTOS together with the Sequencer utility.
BLE_DataThroughput example, it does not contain a .ioc file since it is not generated using STM32CubeMX, So, you can't use it together with the STM32CubeMX.
Best Regards.
