There are no "OTA firmware updates" for Sonicare toothbrushes. There are no other firmware updates either.

Yet. That was the entire point of my post.

Also, how would you know? I have an IOT product that can delta OTA, so only the bytes of the firmware that change are sent to the device, I can do firmware updates that are crazy fast. ESP if it’s just something like turning a feature on.
