BME680: BSEC warning code: 100

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!

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.
