Hey all,
I ran into a problem even Google did not help me to solve. Therefore I hope someone of you can help me out of my misery.
My brother and me are trying to solve this for over a week now and are slowly getting to a quite desperate point.
What I bought:
We have connected the ESP module and the Serial-Converter following Method 2 in this Tutorial:
https://www.hackster.io/brian-lough/3-s ... ule-c514ee
In the Arduino IDE 1.8.9 our Settings are:
I am powering my ESP12E through an external power supply. I even measured the current with an oscilloscope an currently have about 3.25 V at the module.
When booting the ESP Module the blue LED starts to blink slowly. After putting it into the flash-mode by hitting the flash and reset button like show in the tutorial above the LED is turned off.
I hope that is how it is supposed to act.
My problem is:
When trying to upload the "blink.ino" example via the Arduino IDE 1.8.9 always the same error occures:
Also when looking into the serial monitor of the Arduino IDE nothing appears. As I´ve read so far there should be at least a bootup message. In my case there is nothing but a white window.
I also downloaded the nodemcu-flasher software and the espressif flash-download-tool.
Both of them are not able to flash the module like it was the Arduino IDE before.
The nodemcu-flasher does not recognize the mac adress of the ESP12E and the espressif flash-download-tool isn´t able to sync to the module.
I would highly appreciate if someone could give me advice on how to solve my problem an flash something on my new bought module.
