We are comparing a prototype board with first series of production boards and the only difference we see in the performance is that on the production series board the QC sticker is in the range of 1cm of the BME680 sensor. Could it be possible that when the sensor starts operating, it heats little by little particles of the glue, which cause the maximum values? During the prototyping stage we got such values only once - when a sensor was soldered with excessive flux on it. When washed out with alcohol, the problem was resolved.
