MSP432E401Y: I2C Bus: I2C_transfer function

Part Number: MSP432E401Y

I am trying to use the I2C bus and when I am calling the I2C transfer function, it is going into an infinite loop at 

I2C_transfer(i2c, &i2cTransaction)

The function will occasionally return false if I move around the sensor a little bit, but most of the time it stays in that loop. 

Here is my code, basically the same as the i2ctmp007 example program, but with the address and write/read changed.

I have connected the SCL pin of my sensor to PB2, and the SDA pin of my sensor to PB3, and the documentation I am using to figure out the address is below:
