There is an alternative protocol for wireless communications, only problem is that it's Chinese. https://news.ycombinator.com/item?id=42443750
It's not like you can use a Bluetooth classic device to connect to Bluetooth low energy.
Then there's also like Zigbee and etc; I don't think the world is hurting for wireless protocols. Everybody has their own new standard that'll be able to replace the rest lol.
