problematic NodeMCU

Hello all,
this is my first.
My NodeMCU, i think V 1.0, when i try to upload sketches to it using the IDE, i got the following message, i tried messing around with firmware, but obviously unlucky.
the message is too big, so attached as file.

thank you very much for your time

You should always match the XML link to the IDE version that igrr provides: here

Installing with Boards Manager

Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit).

Install Arduino 1.6.8 from the Arduino website.
Start Arduino and open Preferences window.
Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
The best place to ask questions related to this core is ESP8266 community forum: http://www.esp8266.com/arduino. If you find this forum or the ESP8266 Boards Manager package useful, please consider supporting it with a donation.

*. did pasting the link in the prefences..same link as you provided.
*. removed the folder C:\users\user\appdata\local\arduino15
*. and installed IDE 1.6.5

I am also have problems

I have loaded the WiFiscan from the examples for the ESP8622
all work well and then I got this on the serial monitor

this has now happen to two NODEmcu pakages

can someone please tell me what is happening

spycatcher2k:
try setting upload speed to 115200

setting the speed did work out.
but most of the time, i'm unable to program the esp,
i tried hooking it to (Arduino as ISP"through bi-directional 5-3.3v regulator") but still have the same problem.
BUT, by setting the speed to 115200 i was able to blink gpio 16.
on which gpio is the built-in LED ? seems on 0 or 1 ?
thanks alot

Windows can be the most annoying OS. I use Linux and never have serial issues with USB... but try connecting your USB, get the IDE ready to upload, then:

  • Press and hold "reset" on the NodeMcu
  • Press Upload and hold, Release Reset but continue to hold Upload
  • Click Upload on the ArduinoIDE
  • ONLY after the DFU upload starts, you can release the Upload buttonwhike the binary is uploaded

Good luck,

Ray
