Who knows if it's firmware or software

Problem specification

When errstat: 2201! It is difficult to wake up THE CCS811, when the measurement results are incorrect

errstat: 2201 CCS811_ERRSTAT_OK: 152 CCS811: eco2=400 ppm etvoc=0 ppb CCS811: errstat=899=--vhXmrwF--AD-iE errstat: 2201 CCS811_ERRSTAT_OK: 152 CCS811: eco2=400 ppm etvoc=0 ppb CCS811: errstat=899=--vhXmrwF--AD-iE errstat: 2201 CCS811_ERRSTAT_OK: 152

Normal execution:

errstat: 152
CCS811_ERRSTAT_OK: 152
CCS811: eco2=462 ppm  etvoc=9 ppb  CCS811: eco2=462 ppm  etvoc=9 ppb  
errstat: 152
CCS811_ERRSTAT_OK: 152
CCS811: eco2=454 ppm  etvoc=8 ppb  CCS811: eco2=454 ppm  etvoc=8 ppb  
errstat: 152
CCS811_ERRSTAT_OK: 152

CCS811 firmware 1.0.0 is also a problem with the above
