Droplet firmware update
Just a local file firmware update on an Droplet Alpha node. There are two ways to update firmware. From a web server or by uploading a file from the local disk.
Beta and Gamma nodes can be updated over the Droplet protocol. No wifi involved.
These services are available for all Espressif SoCs supporting the Matter protocol, and reduce manufacturing complexities while also safeguarding CSA standards.
