Esp8266 firmware at commands update#

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.Д¬heck the current firmware version can be performed by AT-command: AT+GMR.

The baud rate of the default 115200 baud.

Esp8266 firmware at commands serial#

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.
