Buttonless DFU Timeout

[parco]

Hi,

What happens if a user initiates DFU but never continues the process of uploading an image, does the device sit in this mode indefinitely long?

How might we implement a timeout back to application if say, no image has attempted upload for 60 seconds?

Sounds like a good solution to me

I would have thought that for most scenarios having a timeout on DFU would be a good idea

The bootloader could check if the application memory area is blank, if non - blank it could jump to the application when the timer expired.

Otherwise this sounds like a potential DOS attack, as devices could be sent to DFU and are then out of action.
