Packet Sender

Send/Receive UDP/TCP

Set up network packets based on IP, port, Hex or ASCII data and specify either
UDP or TCP protocol. Results are stored in the live traffic log.

Packets in the log can be easily saved and sent right back out to another
destination. In addition to sending packets, Packet Sender has a built-in TCP
and UDP server running on the port numbers you specify.

1x1 widget support allows sending a packet direct from the home screen.
