I hooked the MLX90614 up to an Arduino UNO according to the instructions here https://learn.adafruit.com/using-melexi ... g-and-test
However, I am not getting and data back (Just a NACK signal on the 9th bit, basically dead air)
Judging from the signals on my oscilloscope, (see screenshot) the SMBus address and read request is being sent properly, with timing and voltage requirements being satisfied. However, no matter what I try, I'm not getting any response from the sensor.
Any help? Thanks.

Does the device address show up in an I2C scan?
