Searching for a way to wipe/clear RAK19007 firmware/memory via hardware

Specifically, via button press or by feeding power to a pin. To be used to wipe private data off of device.

This would be with a 4631

To do this, you would need a different bootloader that supports wiping of the application flash partition via button or GPIO input.
You can’t do that from inside your application.

So there’s no “factory reset” pin in the default bootloader? Thanks for the quick reply by the way!

No, there is no such pin.
