BMP581 I3C Not Working

Hi,
I can get BMP581 to work with I2C and SPI, but not I3C.
Attached is the screenshot for sending a SETDASA command.
It returned NACK for static address.
The static address is 0x46.
I am using SparkFun Pressure Sensor - BMP581 (Qwiic).
What do I missed?

Thanks.

Hi choongay,

The waveform of your host's I3C does not meet the I3C specification. We suggest that you refer to the I3C specification to communicate with BMP581.
