5 Modes of Transmission
5.1 Modes of Sending Data
The data transmission mode of the module includes 5 modes: unicast, protocol unicast, multicast, protocol
multicast, and broadcast.
5.1.1 Broadcasting Mode
In broadcast mode, the sending device sends the data received by the serial port to every node in the network,
and all devices in the network will receive the data.
5.1.2 Multicast Mode
In the multicast mode, first set the group number of the devices in the network in the configuration mode
(grouping, restart to take effect), and the sending device specifies the target group number to send in the
configuration mode (which group to send the data to), and then The sending device enters the transmission mode
and sends the data received by the serial port to the network, and the device with the same group number in the
network will receive the data.
5.1.3 Protocol multicast mode
When the sending device is in transmission mode, the serial port receives data, the first byte represents the
target group number, and the following data represents valid wireless transmission data. There is no need to enter
the configuration mode to configure the target group number.
5.1.4 Unicast Mode
In unicast mode, the devices in the network conduct point-to-point communication through the network
address. The sending device sends the received serial port data to the target address device, and the target address
device can return an ACK to the sending device after receiving the data. Data (the dormant terminal node has no
ACK function).
5.1.5 Protocol unicast mode
When the sending device is in transmission mode, the serial port receives data. The first two bytes represent the short address of
the target network, and the following data represents valid wireless transmission data. There is no need to enter the configuration mode
to configure the short address of the target network.
Note: When configured as broadcast or multicast, the period of periodic transmission is recommended to be greater than 2000ms,
