Based on the snapshot, You got some I2C communication fault that's why the pin is pulled low.
But it shall not impact sequence.

Hello.
It may be easier to execute the sequence in mmWave studio as that will provide the API sequence and you can replicate that sequence in your software. Please refer to the E2E link provided in my first response to see how to enable it in mmWave…
Hi, Navin,
