I have tried to use two BME680 at ESP32 for compare the values for two identical sensors. Using for each BME a seperate I2C bus. If I try the BME680_basic_data_logging sample all is working fine, I get values from both sensors. Using the BME680_config_state sample I will get for the second sensor the iaqSensor.status value "100" back. Didn't found it in documentation / source code - what does this mean? As explanation - I use an array for the sensors - maybe the bsec lib have any problems here with it? Bsec iaqSensor[2]; ... iaqSensor[0].begin(BME680_I2C_ADDR_PRIMARY, I2Cone); iaqSensor[1].begin(BME680_I2C_ADDR_PRIMARY, I2Ctwo); ... void loop(void) {  if (iaqSensor[0].run()) { ... } if (iaqSensor[1].run()) { ... } } of course modified the functions: checkIaqSensorStatus(int n) updateState(int n) loadState(int n) So two questions: - what does mean the errorcode 100 - is it possible to use the bsce lib with two sensors in one sketch? Thanks! Michael EDIT: In the meantime I have seen that it seems not to be possible without major changes in lib to use 2 sensors with this samples.   ... View more
