As for the 3.3V/5V difference, it would definitely be better to either use a 3.3V arduino or put a level-shifter between the two. It's quite possible that I could have used a higher baud rate if I had resolved that difference, but in it's current state it works just fine. displacedtexan – I was using ser2net to configure the serial port to the correct baudrate .. it was a hack, but it also allowed for simple testing from a telnet prompt on the pc.

For my eventual purposes it won't be that big of a deal to have to program via USB, but it would definitely be more convenient to program via the wireless.

I'm doing something similar and have been able to talk to the arduino via a windows virtual serial port driver, but have been unable to actually program it, possibly due to the DTR pulsing that the bootloader wants. I would like to eventually be able to reprogram the arduino's remotely. Have you actually been able to use the arduino IDE or avrdude to program the arduino with the set2net exposed serial port?

I have wanted to do something very similar with my arduino and 520gu. I was stuck on how to get serial info from my arduino using a shell script. Your temp=$(grep -m 1 TEMPF /dev/tts/0 | cut -d : -f 2) code was perfect. Two quick questions... you install ser2net, but I don't think you ever used it... is that correct? Also, the 520gu serial is at 3.3v and the arduino is 5v. Do you foresee problems with that setup? Thanks again! Thanks so much! I have wanted to do something very similar with my arduino and 520gu.

Although I don't see that I stated it explicitly, I haven't had time to find a way to configure the serial at boot (actually haven't done more than look at the output since making this post) .. currently it takes a telnet to the ser2net port after a reboot before the port is configured correctly to use any of the scripts.

Which model of the arduino are you using? And when you say that you connected the TX and RX from the router to the arduino, did you connect it directly to the USB port on the Arduino, or did you use some of the digital pins on the arduino? It's kind of hard to infer from the picture because the shield is in the way. I’m curious. Which model of the arduino are you using?
