Hopefully not an interesting or complicated problem, but it's beyond me.
I'm using an Arduino Fio, two Xbee Series 1's, and the Xbee Explorer Dongle.
I was able to upload sketches wirelessly all weekend and this morning. For no apparent reason (nothing is connected to the Fio save the USB power supply), I can no longer communicate with the device. I've checked the Xbee settings and everything is still all in order - I'm using the settings specified on the Arduino website.
I have the right board and port selected as well.
The error I get is simply, "avrdude: stk500_recv(): programmer is not responding"
Any idea what the problem might be? I'm just trying the simple Blink program currently.
Edit: It works now. No idea why. To the best of my knowledge I didn't change anything, but maybe I just reset it enough times.
