[Ovmsdev] Moving to a production cycle

[Mark Webb-Johnson]

I guess the AUTO stuff Michael has been talking about could handle this. If BOOT (IO0) button held down for X seconds that auto-launch a wifi AP. If held down for Y seconds, then factory reset?

Just a hassle to do, with user having to open the case. Certainly too late to change case design for these first few hundred units.

Regards, Mark.

P.S. I mean “PC” in the wider sense of the word. Not too hard to hook-up on linux, mac, or windows.

I take it that the buttons on the 3.1 hardware aren't anywhere that can be accessed through a proverbial paper clip-sized hole, nor in such a way that a metal paper clip wouldn't be in danger of hitting something live.  Opening my box, I see the 3.0 hardware is not set up that way.  The switches would need to be moved to the back side of the board for that, and the holes put in the case.  Are we too late?

But if the only "PCs" they own are a smart phone and tablet, or in the event that the module is password protected too, use of the buttons would still be required.  Or, they can cash in their "phone a friend" token.  :)  PCs aren't totally obsolete, yet.
