LEDs status indication¶
The two LEDs located on the top-right side of the dongle are used to indicate the status of the BSEC algorithm and IAQ accuracy state:
|Blinks 1x per second||IAQ Accuracy = 0|
|Steady ON||IAQ Accuracy = 1-3 (IAQ value is valid)|
|Short blink||BME680 data read (report sent)|
|Steady ON||ERROR! Problem talking to the sensor|
The BSEC algorithm usually takes about 5 minutes to provide a valid IAQ value (Accuracy = 1) after start.
