Whenever there was no writer on the sensor FIFO the sensor reader started busy waiting because the read() call would become non-blocking and it would just process the remains of the buffer without end. By opening the FIFO as O_RDWR, the sensor reader is a reader and a writer simultaneously, preventing the non-blocking call.
