"CO2_Read" example sketch not working

[bkbalaind]

I tried to use the example sketch for getting CO2 and other parameters.

But what I see:

• CO2 is 500 and don't change
• Temperature is high

I have prototype built by BME280 and CCS811 - this value is correct.

Why this lib not working ?

I'm using VS Code - PlatformIO for project

This happens to me as well.

I found solution - don't use this lib. I don't see native library directly and it works well

The carrier library is using an older version of the bsec library that does not match the latest hardware. I believe the airquality source needs to be modified to support the new bsec.

Thanks for your report @bkbalaind!

I'm going to close this as likely fixed by #84

That fix is in the latest release 2.1.0. If anyone still experiences the problem of the incorrect CO2 readings after updating the library, please comment here and we'll investigate further.

It only reads the value 600.

Hi @tomasalves8. Which version of the "Arduino_MKRIoTCarrier" library are you using? You can see the version in Library Manager.

Are you using an Arduino MKR IoT Carrier Rev2?:

Version 2.1.0

Yes, The Arduino MKR IoT Carrier Rev2
