Hallo,
wenn ich in Blockly eine Funktion anlege in der ich die Werte des Feinstaubsensors SDS011 an openSenseMap schicken will, bekomme ich folgende Fehlermeldung:
{„exit“:„Command failed: 1: Uncaught Fatal Exception“,„process“:"/tmp/accdda8ffb162b883121133a1ec701be/sketch/sketch.ino: In function ‚void PublishOSM()‘:\n/tmp/accdda8ffb162b883121133a1ec701be/sketch/sketch.ino:121:33: error: ‚pm‘ was not declared in this scope\n addMeasurement(SENSOR_IDRID,pm.pm25);\n ^~\n/tmp/accdda8ffb162b883121133a1ec701be/sketch/sketch.ino:121:33: note: suggested alternative: ‚Pm‘\n addMeasurement(SENSOR_IDRID,pm.pm25);\n ^~\n Pm\n\nError during build: exit status 1\n"}
