Deep Sleep
Posted: Thu Apr 18, 2019 5:35 pmHi,
I am trying to use Deep Sleep on my Wemos D1 Mini in order to be able to use it with batteries. I found many sources online that say the same thing pretty much:
1. Connect D0 and RST with a jumper wire
2. Use the following code:
ESP.deepSleep(5000000);
delay(100);
I have done this exactly. When I run the code, it seems the board does go to sleep for 5s in my case, and wakes up once. It does not wake up after one cycle. Also, I get jibberish on my Serial monitor when it wakes up.
Any help would be greatly appreciated!
If it helps, here is my code:
