HI,
i am using nrf52840.i am sending 500bytes from peripheral to central with the time interval of 100 millisecs. for 5 minutes its working fine,but after 5 minutes the unpairing is happening. i tried to initialize wdt ,its restarting for every 2secs. i want wdt to reset only when it is hanged.
regards,
jagadeesh
how to properly post source code - not as an image:
Hi Jagadeesh,
The screenshot is only showing the initialization of the WD timer. We need to see where you reloading the timer, etc to find out why it times out. Can you upload the project or relevant portions of your code so I can debug it here?
