How to write value to register of NXP P3T1750 sensor with I3C?

[nghiatr]

Hello,
I'm trying to write to configuration register of P3T1750 sensor, I can perform this with I2C protocol but it not successfully with I3C, the sensor still ACK the write command but it NACK the read command to configuration register. With the temperature register i can read value with I3C.

I just want to confirm that this is I3C/I2C sensor but the configureation register only r/w by I2C controller, right?

Welcome @nghiatr, to the community!

Your question so far refers exclusively to a sensor from the manufacturer NXP, so it is unlikely to be answered here - you have posted it in the community for STMicroelectronics products. ST has taken over NXP’s MEMS sensors, but not the I3C/I²C digital temperature sensors.

However, the NXP sensor forum will certainly be able to help you with the problem.

Good luck!
