Ah yes, sorry, missed to see that. We do not have resources to debug sensor related issues unless you can show us that the serial communication is not working as it should. Have you tried to sniff the SPI pins using logic analyzer or similar to check if the pin timings match the specification when you send commands or receive data from the sensor?
