How to use the watchdog when DFU

[roy756456625]

Hi

I opened the Watchdog in the user application,and do nothing in the bootloader.Then when I use DFU,the CPU reset appears.How can I to deal with it?

And when I upgrade willful termination APP(nRF Toolbox),the CPU(nRF52832)is down,and can't work.Do you have any suggestions on how to solve this fault tolerance?

Thank you!

One thing you may consider what I have applied is the WDT settings in the nrf_drv_config.h I use

#define WDT_CONFIG_BEHAVIOUR     NRF_WDT_BEHAVIOUR_PAUSE_SLEEP_HALT

Since bootloader with bluetooth most of the time waits for events, no timeout is occuring for the duration of the update process. Thus far I have implemented 10 second and 30 second timeouts for watchdog and both successfully have enabled to finish the dfu process. I am using nRF51 and legacy dfu.

Thanks for the hint! This is not an active thing for me just now, but maybe some day again I need to test this :)

Hi Sven, can I ask you implement 10second and 30 second watchdog at the same time or separately? if the same time, can you help how to implement that? Thank you
