I was working with my adafruit bno055, and tried to interface it with matlab. I was able to interface both my Uno and my bno055 sensor. I followed the matlab's documentation page to calibrate the bno055 senor. and used the readCalibration status command to see how it went. I got this message on my terminal. I got the following message...
I also followed the offical matlab's tutorial on how to connect the bno055 with matlab in their website. The question is how do I get the system status to be calibrated ?. I also was able to get the sensor system to be fully calibrated using Arduino's IDE. So I know that I didn't recive a fauly bno055 senor.

Have you found a solution? If not, try using the 'Adafruit/BNO055' library instead of the 'I2C'. Initially, I was getting the same error as you. Now I can calibrate the System to 'full'.
arduinoObj = arduino('COM7', 'Micro', 'Libraries', 'Adafruit/BNO055');
I am using MATLAB version 2020b. The 2021b version of the Arduino package does not include the 'Adafruit/BNO055' library.
