nRF52840 Watchdog Without Resetting

[czuvich]

I am trying to use the Watchdog on the nRF52840 as a means to check state of the application via different variables.  If I see the application in a bad state, I would like to then issue a reset.  Is there a way to configure the Watchdog to not actually reset the chip, but rather as a "check if alive"?  Or if I could prevent resetting the chip in the IRQ that'd be great.

Or perhaps I'm going about it all wrong and I should use an RTOS timer to check the state and use the Watchdog as a "means to an end" by making it the highest value as possible for my application timeout.

Hello there,

Please see this explanation of what the purpose of WDT is. The WDT in the RF52840 is explained in the product specification. In our SDK, you can find an example of usage and the WDT Driver API reference. 

Let me know if you need any more information!

Kind regards,
Øyvind
