I am using m5unit v2 which has grove port and uart commination.
I have ultrasonic i2c sensor and tof sensor.

m5unit v2 uses pyserial for codding.
It seems like it's not receiving any response from sensor while connected to the grove port.

So I2C sensor doesnt work with m5unit? and is there a way to enable i2c on the linux kernel of m5unit?
