ESP32 Dev Board Internal/Built-in LED Not Blinking

August 3rd, 2019

I was trying to figure out why the painlessmesh example was not blinking the correct amount of times.

It would only blink when serial communication was active.

All the documentation I had seen indicated that the LED would be on PIN GPIO2 but it ended up being on GPIO1.

That’s all for this short post, just thought I would throw it out there for anyone else looking for why this happens.
