One other scenario might be projects where the majority of the code is Arduino already (possibly even assembly) and the ESP is simply used to allow the Arduino Uno to connect to WiFi. My assumption is that if you need to use an Arduino depending on the type and number of sensors required. c++ / Lua / MicroPython), each with more or less features.
I haven't used this module in a few years, but from what I recall there are multiple firmware options each with supporting different languages (e.g. If it's a basic REST API you can GET and POST some data with minimal payloads it should work on the ESP8266 directly. Power up your ESP and boot it up into programming mode as described above.It depends on the complexity of the firmware and the amount of data you need to load/parse/cache on the ESP8266. You can get if from here.įlash Download Tool is officially supported by the Espressif and works fine. At the time of writing of this post the latest AT version is V1.0 which is based on the SDK v1.5.3.
ESP8266 FIRMWARE OPTIONS HOW TO
In the DETECTED INFO frame you can see the detected Flash size.įull story how to connect the hardware is descibed in here.
ESP8266 FIRMWARE OPTIONS SOFTWARE
Second option is to use Flash Download Tool software that is described below. It is much easier to push the button than hold or connect/disconnect the wire each time you need to re-program the module. Next step is to build a programmer for ESP.
It looks like some modules have even larger Flash so feel free to use those as well, if you are lucky and you have one. Modules with W25Q80 chip has 8Mbyte of FLASH on board. Modules that have chip Winbond W25Q40 installed have 4Mbit of FLASH. 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.
ESP8266 FIRMWARE OPTIONS UPDATE
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. Use SDK that makes possible to write your own code on to ESP8266.This script you can send directly through your UART. Basically if you want to reconfigure your WIFI module you can write lua scripts, load it to the module and your code will be executed automatically after next reboot. The most important feature is lua script support. You can still send string based commands to it but they look different. For example last firmware adds SSL support, more AT commands and many bugfixes.
ESP8266 FIRMWARE OPTIONS UPGRADE
You still have option to upgrade the firmware to the latest version. It is by default supported by stock firmware. You can communicate with ESP8266 using AT commands.There are actually many ESP8266 programming options: Soon there will be tutorials how to change the firmware to NodeMCU and write your own custom firmware. In this post I will cover only AT firmware update. I decided to put everything together ino one blog post. There are many tutorials how to program ESP8266 but many of them are missing with detailed instructions or how to make a programmer for this purpose or does not guide where to get the firmware and tools. When it comes with the factory firmware it has AT interface support that is sufficient to cover all configuration options. ESP8266 is currently one of the most widely used WIFI chip because of its low cost and small number of required external components.
