Hi Paul and Paul,
Thanks. Over the weekend I was able to figure out how to download the OLA SW so I could modify it. And I got that up and running. As a debug step I had taken Paulvha code (in zip above) that he had provided me earlier and inserted it into the bottom of the setup() in the Openlog_artemis.ino file. Concept was to independently try to make this code work within the framework as a test (few debugging steps needed code mods, see below, but I tested all this code standalone and sensor was working). I can't get past the ""Air sensor not detected. Please check wiring. Freezing...". It just stays there. I also tried this after commenting out the autodetect step, (so code skipped the autodetect step). And this did not affect problem. I also tried doing a power off of the sensor and restart as I saw that in some earlier versions of SCD30 code. Very mysterious.....
I will reload the base version of OLA code and select 'd' to see what I get. I will also confirm I am at V1.2.1 of Apollo 3. Code I inserted into Setup() below: (sorry it has other mods in it that I was working on but pay attention to setup().
