Re: Won't wake up from Deep Sleep
This sounds similar to what was discussed at viewtopic.php?t=8383#p47626 and in the GitHub issue linked there.dhust wrote: ↑Sun Jul 25, 2021 10:41 pmAnother interesting thing is that the board does reset, but only once, because the LED on the board flashes after the amount of time I set for deep sleep. I've changed it from 3 seconds to 15 seconds and the LED flashes at the correct time. So why would the board reset but the program not run again?
Re: Won't wake up from Deep Sleep
Wow, that Github issue makes me wonder how we ever get lucky enough to get these dev boards to work. Thanks for posting it, lots hints for when my NodeMCU boards arrive.
Re: Won't wake up from Deep Sleep
It might be the development board that I snapped it into that is throwing off the looks. I looked at a datasheet and the pins seem to be named the same. It also looks the same too. Might be an ESP-12E though but I guess that's just an antenna difference.
Re: Won't wake up from Deep Sleep
My attention was diverted to the 8pin connector, I now see that the ESP-12? is plugged-in.
After reading the Github issue looks like you need a schematic of that dev board and work out how all the GPIO are really hooked-up.
Good luck!

Yeah, that sounds dead on. So now what? Buy random boards off of Amazon and hope they work? Seriously, I have no idea what I should buy now.Christian Walther wrote: ↑Mon Jul 26, 2021 9:03 pmThis sounds similar to what was discussed at viewtopic.php?t=8383#p47626 and in the GitHub issue linked there.dhust wrote: ↑Sun Jul 25, 2021 10:41 pmAnother interesting thing is that the board does reset, but only once, because the LED on the board flashes after the amount of time I set for deep sleep.

Re: Won't wake up from Deep Sleep
Buying random boards off Aliexpress didn't work for me. There appears to be lots of rev 1 chip out there in ESP32 boards. Only by going to a local Micropython meeting did I find out that a bunch of boards that another attendee had had rev3 chips in them. So, I ordered some of those from Aliexpress.
So, now to spend more countless hours seeing if they are easier to work with!
A solution could be a maintained list of different boards that people could up-vote or down-vote like Stack Overflow.

Re: Won't wake up from Deep Sleep
Yeah thanks to open source stuff, now we have a lot more options, boards, revisions, vendors. That's why I love Embedded Systems a lot.

Unfortunately, this also leads to companies making boards with alternative parts to make things a bit less expensive at the cost of things not working properly, or companies not following specs and doing things slightly different.williamhenrick wrote: ↑Tue Jul 27, 2021 10:56 amYeah thanks to open source stuff, now we have a lot more options, boards, revisions, vendors.
Re: Won't wake up from Deep Sleep
It could work but also might be a bit difficult. I bought some chips from Amazon and used the same development board as a person on there. Theirs work, mine do not. Great ratings but for some reason all five of mine I can't even connect to. Well, one time I got one to connect, then tried it again a few seconds later and it didn't. Weird and annoying.davef wrote: ↑Tue Jul 27, 2021 6:33 amBuying random boards off Aliexpress didn't work for me. There appears to be lots of rev 1 chip out there in ESP32 boards.
