#Esp8266 firmware version history update

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.Д¬heck 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. ItвЂ™s now possible to use the mbm utility to upload/run code on the board.To work with RemoteXY the ESP8266 module must have firmware that supports AT commands not less than v0.40. $ flash_esp_image -wifi_ssid mywifi -wifi_password mywifipassword -cloudmanager_server 192.168.1.127 -cloudmanager_port 18266 -name nodemcu1 The following example starts a cloudmanager server on the default port and tells the board to connect to wifi network вЂњmywifiвЂќ using wpa password of вЂњwifipasswordвЂќ and register with a cloudmanager server at our address вЂњ192.168.1.127вЂќ running on the default port of вЂњ18266вЂќ as a device named вЂњnodemcu1вЂќ $ mbm server-start

Run the flash_esp_image utility with the arguments to configure the network and cloudmanager.

The board should now be flashed with micropython and the micropython repl prompt will be available on the serial port.ДЇlash the board and configure it to automatically start as a cloudmanager client Verifying 0x8734c (553804) bytes 0x00000000 in flash against /tmp/cloudmanager-micropython-esp8266/local/lib/python2.7/site-packages/cloudmanager_micropython_esp8266/firmware/firmware-combined.bin. Run the flash_esp_image utility without arguments.Д®sptool.py -port /dev/ttyUSB0 -baud 115200 erase_flashД®sptool.py -port /dev/ttyUSB0 -baud 115200 write_flash -verify -flash_size=32m -flash_mode=qio 0 /tmp/cloudmanager-micropython-esp8266/local/lib/python2.7/site-packages/cloudmanager_micropython_esp8266/firmware/firmware-combined.bin.This is the simplest option, the utility will attempt to guess the serial port the device is on and flash it. To just flash the image to the board, if the are no other serial devices installed
