Update firmware¶

On this page you can update the firmware of the Gateway. First you can download the latest stable version and then upload the bin file or another bin file to the Gateway.

Caution

The Gateways S32 and E32 are based on the ESP32. Always chose the ESP32 bin file!. If you upload the ESP8266 bin file you will brick the Gateway and you need to use Platform I/O or the ESP loader to install the correct firmware again.

If your Gateway works fine and there are no significant new features, its not recommended to update the firmware just for the sake of updating. Some firmware versions are not stable and can give stability issues.
