Can anyone share ideas on how to implement a method to recover from a failure to resume with a hard power cycle?
Phones, PC’s all do this usually by a long press & hold of one or more buttons.
Currently I have a GPIO key configured to resume. This works great until it does not.
- Batteries in device are NOT accessible by the customer.
Dose this require addition of a microcontroller or even a 555 timer to monitor a button for press and hold 10 seconds ?
Thanks in advance for any suggestions,
