9.1 Advanced Communication in bqStudio

To communicate with the gauge in bqStudio, navigate to the Advanced Communication window. This window allows the user to send read and write commands to the gauge for easy communication with the gauge over I2C. The I2C Address of the gauge, visible in the DashBoard window in bqStudio, and the Start Register are needed for each Read and Write command, and can be written in the text field. Read commands require the Number of Bytes to Read and Write commands require the Bytes to Write to be specified.
