Start-up behavior
When the power supply is connected, the status LED only lights up red briefly
and then immediately switches over to continuous orange light. If, however,
the orange continuous light stage is not reached, the firmware is not started
up and there is thus a firmware error. After successful establishment of the
connection, the status LED lights up green.
