I am having trouble getting an ACK from the FXOS8700C. It seems like it should be pretty straight forward. I am using the BRKT-STBC-AGM01 with my own MCU and even tried two boards in case one was damaged. I referenced this post as well: 


My connections on the below board:


J3.1, J3.3 - Vdd (3.3V)

J3.2, J4.5 - GND

J3.4 - SCL

J3.5 - SDA



Here is the scope capture:



I cannot communicate to either sensor. My board communicates fine to other connected sensors. 


Any ideas? Thank you.
