Dear Bluetooth SIG,
Thanks for releasing your newest specification for mesh networking over Bluetooth. I'm sure you believe this will be a great. I have a better idea. Why don't you figure out how to make your existing stuff not suck. In your presser you thrice describe Bluetooth as "simple, secure connectivity". I assume you don't have a car with Bluetooth connectivity, because it's anything but simple. You must never have owned a Bluetooth speaker either, because they require an immense amount of fiddling every time I want to connect. I'd describe the current state of Bluetooth as mediocre.
Why don't you make your existing stuff bulletproof before adding on something as notoriously complex as mesh networking?
