how to install hex-file from openWrt -> Arduino Mini 3.3V

I successfully connected a cheap Arduino Mini Pro 3.3V via serial connection to a cheap NEXX 3020F mini router running openWrt:

Even connected GPIO2 to DTR so i can reset the Arduino from the Nexx.
And i think, all it needs to install a new hex file is to send the binary immediately after such a reset.

Maybe there is already a lightweight linux solution like http://russemotto.com/xloader/

Obvious idea, i want to put a lua webpage onto the Nexx to upload a lua script for the Nexx and add a hex file as attachment to be installed on the Arduino which will take care of all the io. All wireless :slight_smile:

the Roland,
Ideas welcome
