Off: The module is not powered on, the
module power supply has failed to operate or
a serious hardware fault has occurred.
Fast flashing green (4Hz): The hardware
initialization is not done yet.
Slowly flashing green (2 seconds on and 2
seconds off): The hardware initialization is
done, but the module has not entered the
normal software initialization flow.
Normal Flashing green (1 second on and 1
second off): The module is operating normally.
Steadily on: The software initialization has
failed and the service cannot be run normally.
Fast flashing green: The module is in the
loading status.
Steadily on: Module loading has failed.
Fast flashing yellow unsteadily: The module is
operating normally, and the data is being
transceiver between the module and the host.
Off: The module is operating normally, and
there is no data being transvalued between
the module and the host.
Green: The module is booting the system after
power-on.
Off: the module is operating normally.
Fast flashing green: The module software has
failed in the application for memory, and the
service cannot be run normally.
Off: The module is operating normally.
