PACKET SENDER LOG PACKETS CODE

Wireshark shows a bad checksum to my code as well to the packet sender app, the difference is that when I use the packet sender it works despite the bad checksum. Way it works with packet sender but not with my code.ģ. I KNOW the 2 last chars in the packet sender is 01 and in the JAVA code isĠ0, it's OK! one turn the light on and the other one off, either I'm trying to run the code in the office network.Ģ. Now just so you'll can understand my problem better, here are some printscreens:ġ] - The wireshark printscreen when I run my code.Ģ] - The Packet Sender with all the data to send.ģ] - the Packet Sender log in which you can see it sent the packet and it did what itĤ] - the Wireshark monitor when I run the packet sender application.ġ. Create a datagram socket, send the packet through it, close it.ĭatagramSocket dsocket = new DatagramSocket() Initialize a datagram packet with data and addressĭatagramPacket packet = new DatagramPacket(message, message.length, Get the internet address of the specified host HexBinaryAdapter adapter = new HexBinaryAdapter() īyte message = adapter.unmarshal('020000c818010000020300') Since the light isn't turned off with my code and only with packet sender I understand that something is wrong, but I don't know what.

When the packet arrives to its destination it turns off one of the lights in the office (like in Home automation). Create a directory for the frequency you want to transmit on. The mainframe's radio has a limited range, though, so it won't reach everything. Until now I used a program called 'Packet Sender', and it worked fine, but my boss asked me to write a code in Java that does the same. Sending packets using the mainframe's radio You can use DWAINE to send out packets over the air. I'm trying to send a UDP packet over a local network in my workplace.
