ESP32 DOIT reset procedure
/One of the things I like about WEMOS ESP devices is that they can be reset into boot mode via their usb serial connection. However, I’ve also bought a bunch of these ESP32 DOIT devices which are really cheap, which is nice, but you need to boot them by hand whenever you want to transfer new code into them. I thought I’d write down the process, since I seem to keep forgetting it:
1. EN down
2. BOOT down
3. EN up
4. BOOT up
Do this while PlatformIO (or Arduino) is trying to load a program into your device and it should connect and work.
