How can I upload a sketch wirelessly, from my MS version 7 PC, to an Arduino Mega 2560 about 60 feet way in the garage, via WiFi, Ethernet, virtual USB or some other means? I can Cut, Edit and Paste code but I’m not an expert at this stuff. Is there one or more boards or boxes that can get the job done?
Try the Arduino forum.
I haven’t seen anyone sketch load over Ethernet yet. The only ways I’ve seen it done are with the Arduino BT and using Xbee modules. The issues with those being that both have a max range under 60ft, the Xbee method in particular has a range of about 5ft before it starts getting upload errors. Please do post if you find any mention of sketch loading over Ethernet.
