Modules with W25Q80 chip has 8Mbyte of FLASH on board. Modules that have chip Winbond W25Q40 installed have 4Mbit of FLASH.
#Esp8266 firmware .ino how to#
There are two options how to detect flash size – check the chip or let the software to ask. First modules were assembled with 4Mbit of Flash and for them you need to use a lot older firmware version.

We will cover all three above mentioned options using Windows based tools.Īt first make sure you have a module that has at least 8Mbit of Flash on board because newer firmware versions do not support anymore modules that have less memory. It is possible to program ESP8266 either in Windows or in Linux.

For example connect just some external sensor through the UART or I2C interface to it and module starts living its own life by checking sensor data and sending update over the network. There are about 30 examples together with SDK how you could use your ESP8266. You can use either stock firmware or RTOS based firmware as the basis and build your application on top of that.

#Esp8266 firmware .ino upgrade#
You still have option to upgrade the firmware to the latest version. It is by default supported by stock firmware.

The more complex solution is to run a script on the server that deletes the file automatically, but that’s really beyond the scope of what I use HTTP updater for, so I’ve never bothered. The easy solution is to delete the updater file once it’s been installed. Not really a problem, but probably not what you really want. The only drawback is that if you leave the updater file where it is, the ESP will keep reinstalling it every day at 2am.

At 2am the ESP will check to see if there’s a file in your specified URL location and if there is it will install it and reboot. Log in to your free hosting account and navigate to /public_html and drop the file in there. Update your code to use the http update URL of http//:/ and put some code in there that gets your device to check for updates every 24 Hours at a specific time of day (2am maybe).Ĭompile the code and find the path for your ino.bin file you see this in verbose mode) pick-up the file and rename it to
