What you are going to learn
This tutorial will show you the Announce service and how to use it to discover the Flyport IP.
The Announce service is an UDP broadcast service.
When a Flyport connects to the network, it sends UDP broadcast the following message:
PICUS <- Host name
00-1E-C0-0E-6C-74 <- MAC address
DHCP/Power event occurred <- Only for the connection
MAC address can be set through the Wizard.
The message is sent from the Flyport port 2860 to the port 30303 on the router.
To test the service, you can use any software for sending and receiving UDP packets.
We do the tests with with TCP/IP Builder software.
Announce service at the connection
Open the TCP/IP Builder and write in the text-boxes:
Local IP -> IP of the PC
Port -> 30303
IP -> 255.255.255.255
Port -> 30303
Now check UDP option and Broadcast optnion and create the socket.
After the switching on of the Flyport, the Annuonce message is sent automatically and in Receive data it is possible to see the message.
To know the Flyport IP it is important to active the debug clicking on the "Debugging..." button and to reset the Flyport
[From: 192.168.1.130:30303 >]PICUS <- Flyport IP
Request an Announce message
The Announce message is sent every time that a character D is trasmitted to the port 30303.
It is possible to send this data to the Flyport IP or to 255.255.255.255 (this IP address is the same as writing "this network")
