when I run the code for the mention sensor, I get: "Could not communicate with the sensor!!!"
the hardware is a Teensy 3.2 using I2C bus 0 (pots 18 and 19)
I know the i2c port works because I can talk to a BME280
using a I2C master (Total Phase Aardvark) with i2c address of 0x57 (7 bit) or 0xAF (read address) I receive a no ack on the 9th clock.


any thoughts?

Hi Richard,

It sounds like there is probably a hardware issue going on here. Are you making sure to connect the RESET and MFIO pins along with your I2C connections? Also, to make sure there are no connection issues, can you please take a few photos of your sensor breakout and the circuit you have it in with your Teensy and attach them to your reply? Please do your best to make sure they are clear and well-lit.
