Thanks Ciprian, that's good to know.  Seems to me there's a fundamental design flaw that prevents the sensor from operating within specification. If they can't fix it in software, then perhaps the solution is to issue a product recall, and redesign the boards.   ... View more

Just over two weeks ago I contacted Arduino regarding a refund under warranty. They said they will discuss the issue with Bosch.  It seems there is some issue as to who 'owns' the problem. ... View more

Thanks Ciprian. I think there's a massive question as to where the error is coming from, whether it's self-heating, or a software issure, or chip-dependent... and then whether the BSEC air quality values can be trusted. My guess is that they are derived (in part) from temperature and humidity, and are therefore equally inaccurate. From my perspective, the sensor is currently useless. It looks like Arduino provide the warranty. Next week I'll move the discussion over there, and request a refund.       ... View more

Hi, I wonder whether you have an update on this issue? Currently, the Nicla Sense ME is essentially useless, I can guess the temperature more accurately than it can. If no update is available soon, I'd be happy for a refund or recall. ... View more

Not a problem, This is the result of:  ioreg -p IOUSB -l -b | grep -E "@|PortNum|USB Serial Number" Nicla Sense CMSIS-DAP@14100000  <class AppleUSBDevice, id 0x100002545, registered, matched, active, busy 0 (1055 ms), retain 18>           "PortNum" = 1           "USB Serial Number" = "CC57804E" ...
