Awesome. Thanks for pointing out Serial. I installed the trial and it Just Works™ with the Adafruit's serial cable. It's not perfect though:
- I haven't figured out how to send files to the Pi with it. Usually I would use
scp. - When I was done I ran
sudo poweroffbut I'm not sure if it worked. "reboot: Power down" but the red light remains on. - It also blocks use of HATs since it's using GPIO.
It would be good enough to get WiFi configured for a headless Pi without needing a separate keyboard.
The Airport Express is a good idea too. I've used one for travel before but I no longer have one. It does make me wonder about configuring the Pi itself like a router with a network a laptop could join, much like some WiFi-enabled cameras. Again it may be good enough to set things up on a different network that has Internet.
I also wonder what can be done with Bluetooth on the Pi 3 once the drivers are there. Could Serial possibly work with the Pi 3 over Bluetooth?
Nathan.
