Run the application for update firmware Flash Download Tools, correctly configure the uploaded files and addresses, correctly set settings.ħ. This step also allows to check the correct connection of the module.ģ. Send the AT-command AT+RST and AT+GMR for determine the current firmware version and memory size of the module. Connect the ESP module to the computer according to the wiring diagram in this article.Ģ. The sequence of steps for ESP8266 firmware updateġ. To start the firmware update process must press the button "START". COM PORT – select the port that is connected to ESP.FLASH SIZE – 8Mbit or 16Mbit depending on the size of the flash memory.Use the following table to select files and destination addresses: Файл в каталоге bin For each file you must specify a valid address download. In the opening window must correctly chose the downloaded files and setup the connection mode.ĭownloadable files are located in the "bin" directory with the firmware files. Run the application Flash Download Tools v2.4 (the.

Link to the program in our file storage: esp8266_nonos_sdk_v1.4.0_15_09_18_0.rarĪll downloaded files must be unpacked and placed in the directory where the full path to the file contains only Latin characters, ie characters without the language localization. This firmware version began to support AT commands v0.40. You must go to “SDKs & Demos” section and download firmware ESP8266 NONOS SDK version at least v1.3.0. A link to the download page on the official website. The firmware can also be downloaded from the official site. Link to the program in our file storage: FLASH_DOWNLOAD_TOOLS_v2.4_150924.rar Firmware Application for firmware update ESP8266 will use Flash Download Tools v2.4 from official site Espressif Systems. To update the firmware you must download the special tool application and the firmware itself. To use the module in normal mode the pin CPIO0 must be disconnected.Ĭheck the current firmware version can be performed by AT-command: AT+GMR. The baud rate of the default 115200 baud. The serial port monitor need be set that command line will be send with final NL and CR chars both. Very suitable the serial port tool into Arduino IDE.

To send AT commands and view the responses need to use any software serial port monitor. If this pin connect to ground when module is works, module will not set into firmware update mode.

The module will set in firmware update mode when CPIO0 pin was connected to the ground at the time of power on. When this pin is connected to the ground, the module is run to the firmware update mode. When this pin not connected the module is run in normal mode and it answers for AT commands. Pin CPIO0 of ESP8266 determines the run mode of module. This output should provide the necessary current of at least 200mA.

The adapter must have an output 3.3V power supply for ESP8266. Pins TX and RX are connected to ESP8266 one to one but not crosswise as if they were connected to the controller in run mode. For this the RESET pin connected to ground. When using the Arduino as converter the ATmega is set into reset mode and only the internal USB-UART converter is active. The module can be connected via the Arduino board, or through a USB-UART adapter. To check the version of firmware, as well as to update the firmware, need to connect the module to a computer via serial port. To work with RemoteXY the ESP8266 module must have firmware that supports AT commands not less than v0.40.
