Hi @jichen ,
Sorry for late response.
I checked the value and your register value is wrong.
Your ODR setting is "reserved" if you set 0x00 in reg 0x40. Please check our datasheet.

If you are using our API, it shouldn't do that.
Are you really using our API? Then, could you share your whole source?
Thank you.
