Reposing this from my thread on the HPR forum for more visibility, and to help someone else who may search for the same thing. I recently assembled an Eggtimer Classic. When I connect the USB, my PC assigns it as COM6 and I am able to find the device using PuTTY as my terminal. The Eggtimer powers on and the Flight Settings screen is displayed. After that, the unit starts beeping again and won't stop. When I press CTRL-Y to perform a memory reset to initialize it, nothing happens. It doesn't show the next screen to prompt pressing and holding the button on the Eggtimer, nor does it show a warning or any other message. Any thoughts?
