Not getting any PM data after flashing new FW 3.1.4 to O-1PST unit

[lubos]

Hi,
after I flash new FW (from 3.0.9 to 3.1.4) there are no readings of any PM on local API as well as on the air gradient portal. My unit is O-1PST

I haven’t try reset to default yet, maybe there are some useful informations what is failing inside the unit. Is it possible to take a logs via API?

Anyone saw such behaviour? If yes, was it bad sensor or SW problem?

Thank you.

Regards,

Are other values coming in properly like Temperature and CO2?

Yes, everything is being delivered except of PMs.
