What is the maximum watchdog period? I saw some comments about fixing it in the ESP-IDF to run for more than an hour. I am up to about 80 minutes and was wondering when I was going to hit the limit. I assume that the WDT uses the RTC timer when in deepsleep(). |

The maximum is infinite of course (don't enable the WDT). I am certainly not a MP expert but given the timeout arg is in millisecs then I would expect the maximum time to be 2^32 / 1000 / 60 / 60 / 24 = 49 days which is obviously kind of pointless however. |

I vaguely recall a 32 bit unsigned int but could not find the reference. Thank you for clarifying that. |

There is no watchdog active during deepsleep(). I think we already discussed this in #10498. |
