5. Sending and receiving method

The data transmission mode of the module includes 5 modes: unicast, protocol unicast, multicast, protocol multicast, and

broadcast.

In the broadcast mode, the sending device sends the data received by the serial port to each node in the network, and all

devices in the network will receive the data. The minimum broadcast period is 500ms.

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. The device with the same group number in the network will receive the data, and the minimum

multicast period is 500ms.

When the sending device is in transmission mode, the serial port receives data, the first byte indicates the target group

number, and the following data indicates valid wireless transmission data. No need to enter the configuration mode to

configure the target group number

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 to indicate that it has received the data. Data (the dormant terminal

node has no ACK function).
