Currently, it seems like I can only use 4 heater profiles/sensors at a time when collecting data. That is, when I create a config file, I can only select 4 sensors. Is it possible to use all 16 profiles together at the same time? This doesn't seem possible with the AI-Studio, but is there a work-around?
I believe that you are asking about it based on BME688 dev kit.
You can select maximum 4 heater profile for data collection and 2 sensors will be assigned for each profile.
Therefore, technically 8 all sensors are running.
But, no we don't have solution to run all 16 profiles right now.
