After much effort, I now have 9 of my 10 OAKS up and running. I had to manually add most of them to the Particle cloud. The 10th one is the one I hooked up to do a factory reset with an FTDI board. I'm not sure if I can recover that one, but I will try. I came to realize that despite what the DOS screen was telling me about disconnections and so on, as long as I was seeing the sets of three blinks, I had successfully downloaded the firmware. After that, I simply had to run the manual program, usually three or four times to get them onto the cloud. During the manual claim process, I also had to cycle the power on the boards, sometimes 2 or 3 times.
