You should have TP3 wired to the indicated pin. Is that what you have?
Grove connector just provides more control over the on/off on the USB Power Control. Same hysteresis on that board as you have.
Thanks for the reply.
Please the pic attached. Purple jumper wire. Connected correctly I think.
To me. It seems like the watchdog just always has an on signal. The patting the dog doesn't seem to be needed. I guess that's why it didn't reboot when the script crashed.
Interestingly. Connected as in your pic above. All runs. But as I said doesn't reboot when crashed. However if I move the pin on the watch dog to the pin right next to it the whole system buzzes and won't start.
