Hallo zusammen,
ich habe folgendes Problem:
Ich habe die senseBox mit Blockly “programmiert”.
Wenn ich lediglich das hochladen der Sensordaten auf die openSenseMap programmiere, klappt alles.
Wenn ich lediglich die Ausgabe auf das LED-Display programmiere, klappt alles.
Wenn ich beides jedoch hintereinanderhänge, lädt die SenseBox lediglich die Daten des ersten Sensors hoch, die restlichen Sensordaten fehlen. Die Ausgabe auf dem Display funtioniert einwandfrei.
Was mache ich falsch?
Vielen Dank für eure Hilfe und Viele Grüße
Sebastian
