Arduino Forward Serial to Telnet With ser2net on Tplink TL-WR703N Running OpenWrt

This is how I used a Tplink MR703 running OpenWrt Backfire to forward the serial port with the Arduino Uno to a telnet port.  This could be used as a cheap alternative to an ethernet shield or connecting the USB to your computer.  I was able to send commands to my Arduino via telnet over wireless network with the MR703 in client mode.

Setup

Install ser2net:

Start ser2net:

Now you should be able to communicate with your Arduino on port 8082.  Open up a telnet window and connect to your router.

Start on Boot

Next I will show you how to set it up so that ser2net will run on boot.
