4.1.5 UDP tunneling mode operations

The UDP tunneling mode operation is similar to that of TCP server/client mode except that it is based
on UDP protocol and only one pre-defined remote host is able to communicate with the HelloDevice
Pro Series. Users do not have to configure the parameter of inactivity timeout, since UDP is a
connectionless protocol.
1) Operations
If a remote host sends a UDP datagram to the UDP Local port of the HelloDevice Pro Series, it checks
if the IP address of the host is the same as the pre-defined Destination IP address. If the IP addresses
are the same, the HelloDevice Pro Series transfers the data through the serial port. Otherwise, the
HelloDevice Pro Series discards the incoming UDP datagram.
If there is any incoming data from the serial port, the HelloDevice Pro Series transfers the data to the
remote host defined as Destination IP & Port. Although the remote port is not open, the HelloDevice
Pro Series does not transfer the data again.
2) Parameters
Local port
The concept is the same as that of TCP communication. See TCP Server mode operations in
the section 4.1.2 for details.
Remote IP address (or domain name) and Remote Port
The concept is the same as that of TCP communication. See TCP Client mode operations in the
section 4.1.3 for details.
