Description
RAK12039 PM values transmitted and decoded have all PM values set to 0 when sent to MQTT broker.
Reason:
Most likely a change in the protobuf (not sure) where additional "has_pmxxx_standard" and "has_pmxxx_environmental" validator fields were added to the air_quality_metrics structure.
But AirQualityTelemetry.cpp does not set these validation fields to true.
This results in sending all PM values as 0 to the MQTT broker.
Fix:
In AirQualityTelemetry.cpp ==> bool AirQualityTelemetryModule::getAirQualityTelemetry(meshtastic_Telemetry *m) the validation markers need to be set to true.
