No. The uploaded program will not disappear after power off. When power is on again, the uploaded program should start again with setup().

- Sat May 13, 2017 3:25 am #65878 Make sure to pull up the programming pin (GPIO 0 at least on ESP12) after uploading the code.

The uploaded program will run once but when you reset ESP and if GPIO 0 is still pulled down the ESP will wait for new software.

So after upload, pull GPIO 0 to HIGH and hit reset. That should do it.


If you lose the WLAN connection for any reason I think you have to reconnect yourself. It doesn't do it automatically. So periodically check if connection is there if not then reconnect.
