Go to Kaa UI -> Device Management -> Software OTA and add new software definition pressing Add software version. Remember the link, we will need it in a moment.įirstly, we should provision the initial firmware that our device has by default, from the factory, for example. Upload the binary and get its sharable link. This is exactly what we need as in this tutorial we want our ESP32 to download firmware binary without extra authentication. Go to your Kaa Cloud account -> Files and choose bucket suffixed with the public.Īll files stored in that bucket are publicly available.

Next, we should host it on the HTTP server.ĮSP32 is also able to download its firmware from the HTTPS server but to keep things simple we chose HTTP. This is a new firmware that we are going to update our ESP32 to. If you use Arduino IDE choose Sketch -> Export compiled Binary.Īfter the compilation is done, choose Sketch -> Show Sketch Folder. Playbook Compile and host new firmware binaryĬompile and upload the new firmware binary file to Kaa File Management.

You know how to connect your ESP to the Kaa platform.
