5 Data receiving and transmitting mode

5.1 Data transmitting mode

The data transmission mode of the module 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 (including itself) in the
network, and all devices in the network will receive the data.

5.1.2 Multicast mode

In multicast mode, first set the group number (for grouping) for the devices in the 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 in the network will receive the data.

5.1.3 Unicast mode

In unicast mode, the devices on the network perform point-to-point communication through the network address. The
sending device sends the received serial data to the target address device. After receiving the data, the device with target
address can return an ACK to the sending device to indicate that it has received data.

5.2 The output mode of the received data

The output mode of received data refers to the method of serial port outputting data after the module receives
wireless data.

5.2.1 Transparent output

If the output mode of the device is transparent output, the module will output the original data through the serial port
