could you provide bcf-generic-node information for VOC sensor?
the example project for VOC is here
You can find this firmware in the Playground and flash the binary. The firmware after pairing sends TVOC data every few seconds. It is possible to connect LCD Module to draw graphs.
The VOC is not implemented in the generic firmware, because the sensor itself is not ideal for low power. We suggest using USB Adapter or Power Module to power the Core + VOC.
The VOC needs an hour to stabilize, ideally 24 hours.
THX for explanation Martin!
