LAUNCHXL-F28379D: Simulink, communicate using I2C bus

I've read the example on matlab that shows how to use the I2C blocks to communicate. (matlab link given below)

The problem is that i cant get it to work with the BNO055 IMU sensor. I've changed the relevant register address and slave address.

The sequence as stated by the BNO055 datasheet is:

1. Send a Start Bit
2. Send the Slave Address
3. Get an Ack back from the Slave
4. Send the Register Address
5. Get an Ack Back from the Slave
6. Send the Data byte
7. Get an Ack back from the Slave
8. Send a Stop Bit.
