BF430 Tunneling mode setup
(also called peer-to-peer mode)

changes to the data structure. The following two examples are to most common setups for tunneling mode:
Serial tunneling between computer and serial device:
Serial tunneling between two serial devices:

SERVER unit, (or use the default port 50000)
4. In the ‘Remote Host IP Address’ field enter the IP address of the TCP SERVER unit,
in this case 19.168.168.125
You are now able to communicate in serial tunneling mode.
