Please refresh me on the function of the watchdog timer.
While the dongle may be powered up, can traffic needs to be sent to the Widget at least once every three seconds or the watchdog will fire.
This watchdog is here to account for a number of possible system issues. Some of them are (1) CAN-Do is not hearing IHU CAN traffic so it assumes it is not well and resets or (2) the CAN Do for some reason locks up and can't receive CAN traffic in which case, again, it resets.
The only CAN traffic that resets the watchdog timer is 'configure' messages (Heartbeat traffic in CDNC terms). So set the heartbeat rate for something shorter than 3 seconds and you will not see any watchdog resets.
This description help?
