Last updated 3 months ago

First download laatest firmware.

With the help of esptool.exe (), 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.
