The topic today is how to burn on the ESP8266 a custom rom named the NodeMCU. You are probably a fan of the blog ) or you already know what the ESP8266 is.ДЇor those of you who don't know what a ESP8266 is, it's a small WiFi module with an arm processor and it has all the functionality of WiFi excluding ssl.ДЄlso it's Arduino compatible and it's the most cheap arduino compatible WiFi module there is.Д«ut on this post we are not going to mention arduino (more than we have to at-least).

So, I'm guessing that if you stumbled upon this page, esp8266 needs constant current too.Д¤.)Note: В another link that might help you to solve the problems with esp module.Menu Flashing the NodeMCU firmware on the ESP8266 (Windows) - Guide 13 January 2015 on ESP8266, Flash, Firmware, Windows, WiFi, NodeMCU, TutorialД®DIT (07-Mar-15): If you own version 12 of the ESP8266 or any version where more GPIO are exposed read here about some additional info for flashing the firmware. ДЈ.)make sure you use either a buck or a 3.3 regulator. please avoid using arduino or computer for vcc.Дў.)check the circuit thrice and always while uploading firmware try to manually reset esp8266 by making chpd gnd for some time and put it back to vcc. download this from the link given.ДЎ.) Power esp 8266 from external power supply.

Have some patience until it says finish.Д®splorer is a software specially made for esp8266 wifi module.you can upload lua code or AT commands on the esp8266 by using this software. ДЎ.)Download the software from the below linkДў.)Now just browse the bin file you want to upload on esp and do not change any of the settings exceptВ the com port and change baud rate to 115200В and click on start.

#Esp8266 firmware update problems install

There are two software to install the bin fileВ on soc of esp8266 ,The second method is by using esp flash download. Step 5: Using Esp Flash Download Toll V0.9.3.1 To change the baud rate you can do this 'AT+UART_DEF=9600, 8, 1, 0, 0'.Now enter 'AT+GMR' and check the firmware version.

#Esp8266 firmware update problems serial

enter 'AT' in serial port and you will get 'OK'.

Check the at commands on different baud rate ,most of the esp works fine on this 115200 baud rate.

Now plug your Arduino back to pc and open serial port.

now just remove GPIO 0 wire that was connected to GND ,you can connect it to VCC or leave it like this. Its very important to get the mac address. use the reset pin and put it to gnd for 2 seconds and then remove it from gnd and re flash it. you have uploaded latest firmware to esp8266.

Then just click flash button ,if everything is fine the flasher will show you the status of download and also your esp 8266 module led will blink very fast.

Open the software and one by one add the bin files in it.

And then connect esp tx and rx pins on it

Upload the blank program on arduino if using.

The connection will remain mostly same for esp8266-12 to run it in flash mode. I used Arduino instead of cp2102 module, and I had no issue in communication. I found daflabs instructables best for this module so far

connect tx of arduino to any other hv pins out of 4 pins ,corresponding to the pin you have connected tx ,connect rx of esp to that which will be Lv pin.

connect 3.3v of breadboard power supply to Lv pin of logic level.

connect 5v of breadboard power supply to hv pin of logic level.

Tx of esp is connected to arduino rx via voltage divider Rx of esp is connected TX arduino directly To prevent this from happening you can do two things. With this module you can separately give 5v to arduino and 3.3 v to esp8266 at the same time. The jumper is solder between gpio 0 and gnd pin.when not using in programming mode shift the jumper to the empty pin. For this you need to solder the jumper on it. Note:The module do not enter the programming board directly. This is the best way for flashing the esp01 buy this module and get free from messy wires in future. TipQuestionComment Step 3: Connecting ESP to Flash Mode Go to this this link below to find firmware files. This board has built in voltage regulator that handles the proper power. There are two types of board's one with RGB led & Ldr sensor and other with just breakout pins. This is most likely the problem lies whenever uploading the new firmware or when you are using the esp8266ДЇor beginners its advised to go with node mcu board's available in market.

As arduino maximum current providing capacity is 40mA while esp8266 draws 250mA.

If you are using esp8266 with arduino, try not to provide power from arduino.

Esp8266 with raspberry pi or arduino or stm32Д®sp8266 needs a external 3.3 v for working properly.

There are two ways the esp8266 can be used. The ESP8266 module is a cheap Wireless module.It has SOC(system on chip) that is capable of providing wifi to any micro controller/microprocessor.
