Esp8266 firmware update
Persistence Of Vision
ah perfect!! that worked! thank you.
actually i spoke too soon.. it got me to be able to "save to ESP" but with errors.. file.remove("init.lua");Errorfile.open("init.lua","w+");Errorw = file.writelineErrorw([==[wifi.setmode(wifi.STATION)]==]);ERROR
Hi, I'm stuck with trying to communicate with my esp8266 -01.Any ideas on what could be going wrong? I can't upload any lua code. I've followed the firmware flash and done it a few times. I feel like I'm missing something.. - yumach
how are u powering esp8266?make sure you do not power from laptop nor arduino .use an external power supply and then try. - parmarravi

Hi All, After Reading the Instructable and doing it on 2 diffrenet esp . I always end up with an unresponsive AT. I want to know the easist way to factory reset esp8266. So i can Send AT commsnds.
I had this issue. Swapped USB cords and got to 100%.

I was having the same Issue,I solved this but by pressing the reset button 2 or 3 times (while holding the [PROG] button) when it tries to connect.
Kindly check the power. provided to ESP-01
Thank you for such a nice Tutorial :) !Yeah I worked for me. and solved the following Issues:1- My ESP-01 (Black PCB 1024k) was printing garbage on serial monitor. But after re-flashing that problem is gone !. and the BAUD rate restored to 9600.2- I was failing flashing again and again even I thought I bricked my module (The blue LED was blinking very fast even if there was no Rx and TX wires attached to USB-TTL converter)3- Error occur right after resting the Module "ets Jan 8 2013,rst cause:2, boot mode:(3,6)" also gone. Thank you once again :) !
Please help me in following :I have successfully upgraded firmware in my ESP8266-01, but after upgrading when I connect ch_pd to 3.3v it disconnects my arduino, and LED on uno starts blinking fast, I have tried to add pull up resister of 3k between 3.3v and ch_pd pin, but still id disconnects my arduino.

I'm a complete beginner. I'm using a 201 module (also tried the 01 with the same issues) I flashed the newest firmware called "nodemcu_float_0.9.6-dev_20150704". In Lua Loader I get a page of this gibberish when uploading a file to the esp. In esplorer I get this "Can't autodetect firmware, because proper answer not received. Please, reset module or continue manually..." In case this is a situation with the firmware I also tried the stock firmware with ESP8266Flasher and also v0.9.2.2 AT Firmware. I followed the steps to cycle reset a few times but nothing works GPIO0 is indeed high, GPIO2 10k resistor high, GPIO15 10k to low, reset to high, CH_PD high, RX through a voltage divider. Any other clues? I've spent days trying to get this going.Thanks
Have you solved your problem? I have same issue.
Please Help resolve this error
Hello Experts We have been struggling to execute application on ESP8266 and I tried all the flashing procedure mentioned above but no luck and our esp8266-01 is resetting again & again with watchdog reset errorwdt resetload 0x4010f000, len 1264, room 16tail 0chksum 0x42csum 0x42~ld Setup don startWe have been using below schematic for the connection and here is the part number.ESP8266 01 wifi transreciver D-SUN "USB to TTL" (Blue)We are connecting 2 pencil cells to supply 3.3V to ESP8266. is that correct ? what should be the current ?Please advice how to proceed further.
getting error: FILE="init.lua" file.remove(FILE) file.open(FILE,"w+") uart.setup(0,9600,8,0,1,0)file.close();Error
Yes I grounded the Gpio0 pin
while uploading the code to ESP using Esplorer I get the error stating: "waiting answer from ESP – timeout reached,send abort.".. how to solve it?
Hi Can you tell me if using Arduino needs any special firmware preflashed to ESP or does it do it in-setu while writing the sketch? I am not sure, but does Arduino need NodeMCU firmware to be present to work? Or does Arduino compiles to the sketch to native executable for ESP (in which case probably no need to install separate development tools since using Aurido we can compile C files also stand alone or part of sketch, right?)

I've already downloaded the firmware to esp8266. However, when I disconnect the gpio0 , the com port of the computer disappeared. Any AT command to esp8266 cannot get any response. Is there any solution to this problem?
So if i dont update the firmware, i wont be able to run esp8266 with arduino codes? cause it works when i insert AT commands in serial monitor but when i write a code and upload it, it gives me garbage.
Hi, can you draw the scheme of your setup, because i'm new in this...And, what capacitor voltage do you use...?Thanks..
it is not wroking
Great guide![SOLVED] To all the people having "Failed to connect", this is how I solved it.My setup:1) os: OSX El Capitan2) esp: ESP8266-013) Arduino Uno: DCCDuino clone4) flasher: esptool.py5) connections:ESP--->ArduinoGND(-): GNDGPIO0: GNDEN(CH_PD): 3.3vVCC(+): 3.3vTX: TXRX: RXThis was failing, so the solution was:Add 1000mf capacitor between + and -, and that's it!Hope it helps, I spent more than a day 100% on this, and finally got it working thanks to the above..cheers
