LFR-TCP

lfr-tcp is a bridge between an LFR compatible simulated radio interface and a KISS TNC interface. lfr-tcp acts as a server, accepting one client connection at a time on the uart_port. Over this port, the client can send LFR commands that will be proccessed by lfr-tcp. lfr-tcp also acts as a KISS client. It connects to the server specified by ipaddr and port and sends any packets as KISS commands to that server. It also accepts KISS commands from that server which then are passed as received packets over an LFR interface on uart_port.

com_radio.py provides an example LFR client, exposing the radio_util interface found elsewhere in UBNL code.

Compiling:

There are no external dependencies. Simply:

make

The sole build product is lfr_tcp.

Usage:

lfr-tcp ipaddr port uart_port

Example

In three separate terminals:

nc -l 52001 | xxd

./lfr-tcp 127.0.0.1 52001 2600

com_radio.py 127.0.0.1 2600 tx 10
