The difference with the REAL_COM protocol is that the registry is enabled
and the registry information 31 32 33 34 is filled in. Note that this is
hexadecimal, which means that the actual data sent is the string 1234. If
you need a string display, click the "ASCII" option.
When the device is connected to the cloud software, it can automatically
send the hexadecimal registration package of 31 32 33 34. This
registration method is more flexible, can let the device to adapt to the
existing cloud registration format; However, there is no wildcard like MAC
in the registry, so it is tedious to configure a different registry for each
device. The above two methods of sending MAC addresses and
REALCOM are the same for each device configuration, but they are
naturally different for different MAC registries.
The maximum registered package length is 33 bytes. This mode supports
UDP mode registration packages and heartbeat packages.
Note that if the wifi parameter or multi-destination IP parameter is set, it
will conflict with the custom registry heartbeat packet. At this time, it is
recommended to use the transcode configuration file described in the next
section to realize the registry and heartbeat packet.
