Could you expand upon the libaries. I downloaded one library though the Arduino library manager. You say it's buggy. ANd that we should copy the iot_example libary to the src, but more information is needed. The existing ..Arduino\libraries\BSEC_Software_Library\src has directories of various platforms atmega, esp8266 and also of bme680 The BSEC_1.4.8._Generic_Release_Update has a number of things in it. It has a config directory with the files defining the various generic... Does that need to go somewhere? Then there's the algo directory with a lite_version and normal_version, which I assume are the actual libaries. So do those get copied into the src directory? Inside each of those is a bin and inc folder. And the bin folder has a list of hardware platforms : esp, gcc, MAC, avr etc. Inside of the esp file is esp8266 and four files . SO exactly how is this suppossed to be done?

Just to be clear, you're saying this libary is buggy: https://github.com/BoschSensortec/BSEC-Arduino-library/tree/master/examples What is this library https://github.com/BoschSensortec/BME680_driver/releases and how to use it? That's now been updated to this one: https://github.com/BoschSensortec/BME68x-Sensor-API How do those APIs fit into the picture? As for the bsec_iot_example, it is, at best, very awkward to use. Who wants all those files in their application? WHy can't you make it a good Arduino style library? At least put your bsec_iot_example into a decent library format and example.ino. And you should put a notice on the arduino library that it's buggy.

I hve a couple of questions that could be answered if you had some clear rules defined about using the BSEC library. I have an application where I want to log data evry minute. Currently I average 3 readings at 20 seconds sampling to get the data at the minute mark. I currently have the BME680 running with the Adafruit_BME680.h library and getting the T, H, Raw Resistance, and Pressure, sampling at the 20s interval. I'd like to add the BSEC library eCO2 to that list. So I several questions. 1. Can I run the Adafruit library and BSEC library at the same time? 2. In ULP mode, from what I read, the libary has to be "read" every 3 seconds (ie. iaqSensor.run() has to run every 3 seconds, at which time I could read the eC02 value. And this could be triggered by a timer. Is this correct? 3. In ULP plus mode, I could then also do iaq.Sensor() at the 20 second mark. And very 3rd 20 second read would correspond to a 3 second read too. Is this correct? 4. What isn't clear is what values are really only able to be read at the 3 second interval? Clearly with the Adafruit library I can read at various intervals. So the raw signals are available more regularly. What bout the compensated T and H readings? Are they only at the 3 second mark? 5. I saw somewhere on this forum that one of the iaq values has to be 3 in order for the eCO2 value to be valid. Which one is that? 6. Why isn't some basic info like this in the data sheet or the integration guide. Most of the world doesn't run its software on a busy loop.
