Figure 33 Set registration package
The difference with the REAL_COM protocol is that the registration package is enabled here,
and the registration package information such as 31 32 33 34 is filled in. Note that this is
hexadecimal, that is, the actual data sent is the string 1234. If you need to display a string, click
the "ASCII" option next to it.
When the device is connected to the cloud software, it can automatically send the
hexadecimal registration package of 31 32 33 34. This registration package method is more
flexible, allowing the device to adapt to the existing cloud registration package format; however,
there is no wildcard such as MAC in the registration package, and different registration packages
need to be configured separately for each device, which is more cumbersome. The above two
methods of sending MAC address and REALCOM have the same configuration for each device,
but the registration package is naturally different due to different MACs.
The longest registration packet length is 33 bytes. This method supports registration packets
and heartbeat packets in UDP mode.
8 . 1 . 4 . CONFIGURATION FILE
Support serial server to write a configuration file, so as to realize user- defined registration
package, and can use MAC address wildcard, which can solve the trouble of writing custom
registration package for each device, and there is no limit to the length of registration package.
