- Fri May 10, 2019 6:20 am #82244 hello,
I developed an esp8266 application (c ++) with API arduino. It works fine when I upload it.
How to burn it in the ESP for it starts at boot ?
thanks for answers.

If you're using a NodeMCU or a Wemos (or any other development board), it should run without any alterations or special switch settings.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
