    Hi Nirav,

    Please show me, using a logic analyzer or oscilloscope, the activity on your SCL and SDA pins.

    Are you able to communicate with other I2C devices? Do you have other I2C devices on this bus? Can you share your schematic?

    You may need to reach out to the MCU vendor separately for support with their software platform.

    thanks,

    ren
