Flash firmware

First download laatest firmware.

With the help of esptool.exe (https://github.com/espressif/esptool), the firmware can be flashed onto the ESP module. The ESPTool is available for different operating systems. Firmware.ZIP contains ESPTool for windows 64bit. ESPTool is licensed under GPL v2.

Normally a driver for ESP microcontroller connected to an USB Port is found automatically. If no driver is found, download drivers from links above.

• Download the Firmware.zip archive from links above or from github and extract it to any folder

  • The archive contains the esptool for flashing, the Flashen.cmd script and the two firmware files

  • Double click on the file Flashen.cmd.

  The firmware is now transfered into MQTTdevice flash.
