KC868-A32 I2C communication with arduino

[SixSixOne]

I've purchased a KC868-A32 module and its functionallity is as expected.

I try to implement an I2C communication between the KC868-A32 module and an arduino device in order to control PWD IOs of the arduino through the KC868-A32 module (i.e. through Home assistant).

Could you please provide some instructions or an example on the code for the arduino device?

Thank you in advance
