@attila Thanks.
I am using the h as prefix and still, the readback values from the device is not correct! See picture below.
Note: I have connected SCL, SDA using a pull up resistor to DIO 27 ( 3.3V )
In the picture below- tried to write bytes 1 2 3 , but read back as 2,2,2..
The device Ack's and I see no issue. But the readback values are wrong!
Thanks
