This is a proposal for a new Imp API method similar to hardware.wakereason()
The problem
Today I am wanting to do something in response to production devices being blinked up. The problem is, for most devices it will be their first time being blinked up in a long while, so they will also have to download a software update, and
If there is new Squirrel code available after restarting due to a BlinkUp, the wake reason will be overridden with
WAKEREASON_NEW_SQUIRREL
so I can’t react to the BlinkUp. There is a similar clash between WAKEREASON_SW_RESTART or WAKEREASON_SW_RESET and WAKEREASON_NEW_SQUIRREL. The cause seems to me to be that only one wake reason can be reported, even when multiple apply.
The solution
What would solve my problem would be a new method that could report multiple wake reasons. For example, hardware.wakereasons() could return an integer/bit-array. Instead of
if (hardware.wakereason() == WAKEREASON_BLINKUP) {
// ...
}
I could use
if (hardware.wakereasons() & WAKEREASONS_BLINKUP) {
// ...
}
This would allow developers to more reliably react to events like BlinkUp or new Squirrel.
Also open to any tips I might be missing on existing ways to achieve this goal.
