Firmware – Windows Guide

Download and installation of the driver for the USB-To-Serial Adapter

You can usually find the USB drivers for your hardware on the homepage of the dealer or manufacturer of the device. To make things easier, we have listed the most common links here:

Silicon Labs CP210x for Win/Mac/Linux
WCH CH340G for Win/Mac/Linux

Download of the NodeMCU Flash Tool

Download the latest version of the NodeMCU Flash Tool. You can find it here.

Download the latest version of the Sensate firmware

You can download the latest version of our firmware here as binary file.

Use the Windows Device Manager to find the serial port.

Open the Windows device manager, then open the menu “Ports (COM & LPT)” in the device tree and remember the name (here it is COM3)

If you don’t know which of the listed ports is the right one – try plugging the USB cable or the USB to Serial Adapter in and out and watch which port disappears and reappears.

Use the NodeMCU tool to transfer the firmware to the ESP8266 chip.

Now start the previously loaded NodeMCU Tool, and check the configuration (in the tab “Advanced”)
In the “Config” tab, select the previously downloaded firmware file by pressing the “Gear symbol”.
Then switch to the “Operation” tab, select the COM port previously found in the device manager (here: COM3) and then start the programming process by clicking on “Flash (F)”.
When the bar is full and the green check mark at the bottom left is visible, the flash process is complete.

Please do not forget to restart the hardware manually after programming to ensure proper function.
