Solved. Do not use sciosense/CCS811_driver - a lot of errors in code.

Do you have some examples of errors on the sciosense driver code?

// Flashes the firmware of the CCS811 with size bytes from image - image _must_ be in PROGMEM bool ScioSense_CCS811::flash(const uint8_t * image, int size) { ... // Invoke a SW reset (bring CCS811 in a know state) PRINT(F("ccs811: reset ")); ok= this->write(_slaveaddr, CCS811_SW_RESET, sw_reset, 5); ... // Invoke app erase PRINT(F("ccs811: app-erase ")); ok= this->write(_slaveaddr, CCS811_APP_ERASE, app_erase, 5);

The result is app-erase not executing. After correct this flash exits with error and none blocks writed. I download your code and flash without any problems from first attempt
