2. Group ID：
Code
Group No.
0x0000
The "Group ID" parameter specifies the logical group identity for RFU-2400
devices, and each RFU-2400 module must be set to the same value if it is in the
same group as other modules.
※ Reminder: When attempting to differentiate between different
communication groups, the first priority is to adjust the RF Channel.
However, if too many RFU-2400 groups occupy all the RF channels, the
Group ID parameter is the second priority to be configured when creating a
new group.

P2P/Master
P2P/Slave
Reserved
Two wireless communication modes can be configured, Peer-to-Peer (P2P)
mode and Broadcast mode, as described below.
Peer-to-Peer (P2P) Mode
-
In Peer-to-Peer (P2P) mode, full-duplex (TDD, time-division duplexing)
communication is supported between the two nodes, with the limitation that
only two RFU-2400 devices are allowed to be included in a single
communication group.
Broadcast Mode
-
In Broadcast mode, data transmission is performed via a broadcast frame.
Broadcast mode is suitable for multi-point communication. Although there are
no limitations to the number of RFU-2400 devices that can be included in a
single communication group, only half-duplex communication supported. Since
there is the possibility that data collision can occur during wireless transmission,
a Master-Slave (Question-Response) architecture is recommended.
