@camparite , did you find a solution for this problem? I am facing the same issue on my side.

@camparite, this looks like a similar problem as to my issue with ESP32s here.

You could have a look at my PR that I made to fix the issue here.

Alternatively, you could try a 'hacky' fix by adding the code block below before the code where you include the Omron library:

typedef enum {
    I2C_ERROR_OK=0,
    I2C_ERROR_LENGTH,
    I2C_ERROR_ADDRESS_SENT_NACK,
    I2C_ERROR_DATA_SENT_NACK,
    I2C_ERROR_OTHER
} i2c_err_t;
