5 Advanced Features
5.1 Heartbeat Pack
In client mode, users can choose to send heartbeat packets and customize the heartbeat packet time. The
heartbeat packet can be sent in two modes: network heartbeat packet and serial heartbeat packet, which supports
hexadecimal and ASCII code. It is recommended that you do not configure the KeepAlive time to be less than 60s,
for example, 120s is recommended in the AliCloud manual.
Heartbeat packet sending mode:
(1) The default is to turn off the heartbeat packet mode.
(2), Serial mode -> The device sends heartbeat content to the serial bus according to the set heartbeat interval.
(3), Network port mode -> the device sends heartbeat content to the network bus at the set heartbeat interval.
Customize the heartbeat packet content (maximum support 40 bytes (ASCII) data, 20 bytes (HEX) data)
Custom heartbeat packet sending interval, set to 0 to turn off the heartbeat packet function, set value greater
than zero to turn on the heartbeat packet function, settable range when turned on: (1-65536) seconds, default value
is 0.
5.2 Registration package
In client mode, users can choose to send registration packets and customize the registration packet time
settings.
The registration packet supports the following modes:
(1), MAC address sent when the network establishes a connection with the device (OLMAC)
(2), the network and the device to establish a connection to send a custom registration packet of data
(OLCSTM)
(3), the network and the device to establish a connection, the device to the network to send each packet of data
in front of the MAC address (EMBMAC)
(4), after the network and the device establish a connection, each packet of data sent by the device to the
network is preceded by custom registration packet data (EMBCSTM)
Custom registration packet content (maximum support 40 bytes (ASCII) data, 20 bytes (HEX) data)
【Note】 Please do not use special characters (such as "," "\" "/" etc.) when configuring the registration packet
on the web page, the host computer can configure special characters, but it may cause the web page configuration
can not access.
5.3 Short connection
In client mode, it supports network short connection (the function is disabled by default). TCP short
connection is mainly used to save server resource overhead and is generally applied to multi-point (multiple clients)
to one-point (server) scenarios.
The TCP short connection function is used in TCP Client mode. When the short connection function is enabled,
the device will only request to connect with the server when sending information, and after the connection is
