ESP8266 Community Forum

- Sun Jan 05, 2020 10:32 am #85162 I have an ESP8266 in my coffee machine. It has been working nicely for two years and today I wanted to update it using OTA. And it worked, first time. But I made a mistake in the code and now I need to upload again and is stuck. The error I see is "536".

How can I find what 536 means?

- Thu Jan 09, 2020 12:18 pm #85212 This also happened to a second device for me.
Sometimes it said 2144 ( =4*536), but most commonly 536.

But at last, after some 50 tests, it worked.

- Sun Jan 12, 2020 5:18 am #85245 I found the "real" error. I had two espota.py on my computer. The one I used was for ESP32. Funny it worked sometimes. Thanks for helping!
