Hello,
I'm noticing in my bmeraw files as well as my data output from a single BME688 sensor that while running different heater profiles with a duty cycle of 1:0 that I am seeing every so often the gas resistance value: 102400000.000000 on step index zero (and sometimes index 1). I don't believe this is normal as the previous values before it are much smaller. Is there any explaination for why this might be happening?
I have tried five different 8-sensor development kits and two seperate breakout boards with the BME688 and I still see this value output in my data when running with a duty cycle of 1:0. I am assuming this might be due to the profile transitioning so quickly from the last step index temperature back to the first, but I've also tested this using the default config that comes with the dev kits and see the same thing.
All of these sensors have undergone a 72hr burn-in period, but I am still wondering, do I need to allow the sensors to run 5 minutes before I can assume I am receiving genuine data?
Any insight into this anomaly would be greatly appreciated!
Also, here is some data so you can see what I am talking about:
