I’ve been trying to control two LEDs via MQTT for hours.With TheThings Network i just can send 01,02 or 03 and it works. What have I done wrong? Do I have to adjust Payload Encoder? I just got a acknowledged:false.
This is two bytes, 0x30 and 0x31 because you have encoded the printable ASCII digits “01” probably as a result of putting a string (perhaps a value mistakenly converted to a string) through your base64 encoder.
What you want to send is “AQ==” which is the single-byte value 0x01
