I have a fairly standard setup … my ESP8266 sits on an Airrohr circuit board and I have the SDS, a BME and a DNMS attached to it.
All worked fine until ~a month ago. Suddenly the SDS does no longer provide data as it is apparently not recognized by the ESP.

Of course, I already restarted multiple times (soft and hard reset), validated cables etc … Any further suggestions?
Many thanks in advance!
