Here are the captures for ESP32 and ESP8266. As you can see all transactions are exactly the same up to the point where they start reading from the status register (0x1D). It happens at 1.6969926 s and 19.9563494 s for ESP32 and ESP8266 respectively. The only difference is that the duration of reads/writes for esp8266 is a bit longer so I did slow down the i2c_clock of the esp32 but didn't change the outcome. I was wondering if anyone has run this code on an esp32 board successfully?    PS.

As a follow up on this issue, I did some debugging and noticed the issue is nailed down to function read_field_data(...). In this function, because of some reason, the gas_valid_r <5> and heat_stab_r<4> bits in gas_r_lsb (0x2B) doesn't get set!!! Note that all the variables such as calibration data and chip-ID are read correctly from BME680. Also, the written values seem to be ok. I was able to confirm it by reading the same values as they are written. Attached some screen shut from both read and write. Also, the timing is correct. It is interesting that I was able to run the exact same code on an ESP8266 dev-board. Simply, set the Arduino IDE board to  NodeMCU and it worked!! The timing is the same for both boards. It must be a sneaky subtle issue somewhere. Any idea what could be wrong? ... View more

Hi  Thank you for the comment. As you said I updated the library and it solved the "BSEC_OUTPUT_IAQ_ESTIMATE" issue. However, now I'm getting a different error. It seems the compiler cannot find the declaration of the functions in bsec_integration.h, despite the fact that it is included in the main project file. should I set something in the Arduino IDE?
