Photon and TMP102/I2C Issues

Sensors Environmental
1

I have a Photon wired up to a tmp102 Breakout Board that’s on a photon battery shield. For the life of me I cannot get the tmp102 to work with this setup.

“SparkFun Digital Temperature Sensor Breakout - TMP102”

“SparkFun Photon Battery Shield”

The breakout board works when using a Redboard(Uno Clone) and outputting to serial. When following the tutorial below the tmp102 does not work. It’s acting like the I2C communication is failing. Wire.IsEnable appears to be false when the code executes. The boards are wired up properly and the photon is on the battery shield.

When I run the same program while the photon is on a breadboard it works. I am following the tutorial below. I modified the code by removing all the data stream logic to phant. I am publishing an event to particle’s cloud instead. Is something on the battery shield interfering???

There is an I2C device on the battery shield, but it’s not at the same address as the TMP102.

I’m not seeing anything that would prevent the TMP102 working with the shield in place. :frowning:
