Lightbulb: save status on flash #133

Closed leotordo closed 1 month ago

leotordo commented 2 months ago

Hello, is it possible to save status of led (on/off and % of pwm) in flash memory. I want to recover it every time I restart the board. Thanks Stefano

The SDK itself does not inherently support this, but you can store the values using NVS APIs whenever your write callback is invoked or the value changes by some other means and then, on a reboot, restore it from NVS and pass it to the API which creates the characteristics.
