Forwarding the OBDII Adapter via TCP/IP
python source/java/can4eve/scripts/tcp_serial_redirect.py --debug -P 7000 /dev/rfcomm0 115200
--- TCP/IP to Serial redirect on /dev/rfcomm0 115200,8,N,1 ---
--- type Ctrl-C / BREAK to quit
Waiting for connection on 7000...
At this point your OBDLink LX is available via LAN - you can simply do a telnet host 7000 to the server where you ran the commands. The can4eve software can now use the bluetooth device as if it was a Wifi/LAN device
