I'm not using continuous measurement mode with this code, it should be the default values.
Besides this, I have used this same code (with the 7 ms delay between requesting measurements) and gotten good data on the evaluation board. The issue is more that the PCB with the nine magnet sensors will return bogus data, all 1s or 0s, or not communicate at all.
After doing some looking, the oscilloscope shows that when the SDA and SCL lines are not connected to the PCB that has the nine magnet sensors, both lines go between 0 - 5V.
On the evaluation board (the one that has a single magnet sensor), the SDA and SCL lines both go between 0 - 3.3V. (I am connecting the 3.3V line to the sensor).
