I'm managing to upload a sketch to the ESP8266 01. I have been researching on internet but I'm not able to get it.
I have installed the libraries for Arduino IDE and my circuit is the ESP powered by 9V converted to 3.3V using a LD 3.3 converter. I tested the voltages and works fine. Also the led in ESP is on (red). To connect to the computer I'm using a TTL USB cable without vcc connected only for tx and rx.
The commands for the ESP works fine (AT commands), but when I try to upload a sketch it shown the following error:
I also have connected to GP0 (ESP) a button to ground. The circuit is:
9V battery --> 3.3V converter --> ESP---> TTL
Anyone knows about that error and why could be? Because the AT commands works fine. Maybe I need to provide more information but not sure.
My goal is to do this tutorial: https://learn.adafruit.com/downloads/pdf/esp8266-temperature-slash-humidity-webserver.pdf
Another problem that I have following that tutorial is that in Arduino IDE, I cannot setup esptool as programmer, because isn't there. I loaded the same library for esp
