That would be great. I've had a little dig and the reset reason is available. If we could choose to wait only on power on that would be a big help. I know it doesn't address the 'using an external device to shut off the power' scenario but selfishly for me it would really help.

Darn but i wish i could edit my post. I note that some versions of the sdk this reason was set incorrectly - which i'm guessing may be why mmiscool hadn't implemented anything based on it. viewtopic.php?f=32&t=8411&start=8

Would it be worthwhile to poll a GPIO pin and either wait the 30 seconds or not wait based on its state? Let's say it's GPIO16. Just put a pull-down resistor on it then allow a button to pull it high. It's only tested in the first few seconds after power up so the pin is available for general use after that. If I want to interrupt a boot process and prevent an autostart of /default.bas, it's almost certain that I'm still in development and within reach of this button!

Right now as is. Auto start of a program can be disabled by pulling gpio 0 low while it is trying to do its initial wifi connection.

I suppose that a setting could be added to change the boot safe mode time.
