I was glad that I could understand why I could not get the data.
Thank you.

    THERMAL UNIT (MLX 90640) does not work.posted in UnitsI have M5Stack Gray and Thermal Unit. 
 I use Arduino IDE and I installed Arduino core for ESP32 using the board manager.I tried the example sketch that was included with M5Stack library. 
 https://github.com/m5stack/M5Stack/tree/master/examples/Unit/MLX90640I find that the THERMAL UNIT works or not is depending on the version of the ESP32 software. - ESP32 v1.0.0 : not work
- ESP32 v1.0.1-rc1 : work
- ESP32 v1.0.1-rc2 : not work
- ESP32 v1.0.1-rc3 : not work
- ESP32 v1.0.1-rc4 : not work
- ESP32 v1.0.1 : not work
 Only the v1.0.1-rc1, the Thermal Unit works. But I do not find the reason. I want to work the Thermal unit with lastest version of ESP32 software. 
 Please give me some advice.
