5. Transmission mode
5.1 Data transmission mode
The data transmission mode includes unicast, broadcast and multicast.
5.1.1 Broadcast mode
In broadcast mode, the sending device sends the data received by the serial port to each node in network (not
Sleep-End-device
), and all non-sleeping devices in network will receive data.
5.1.2 Multicast mode
In multicast mode, first set the group number (for grouping) for the devices in network. The sending device must
specify the target group number (to which group to send the data). Then the sending device will send the data received by
the serial port to the network, and the devices with the same group number (not
Sleep-End-device
) in network will receive
the data.
5.1.3 Unicast Mode
In unicast mode, devices in network point to point communicate through network address , and the transmitting
device sends the received serial port data to the target address device, and the target address device can return an ACK to
the transmitting device to indicate that the data has been received after receiving the data. .(ACK function is not available
in sleep
Sleep-End-device
node)
5.2 Receiving data output method
The receiving data output mode refers to a manner in which the serial port outputs data after the module receives the
wireless data;
5.2.1 Transparent output
If the output mode of the configuration device is transparent output, the module will output the original data through
the serial port after receiving the wireless data;
5.2.2 Data + short address
When the output mode is data + short address, after receiving the wireless data, the serial port will output the
