Eventually, we will know bluetooth died, and a new hardware and platform will replace it. Its called ZigBee.

It started with only transceiver and earphone and microphone, but now advanced to a mesh with a map to see all the communication nodes and path. This is moving on to industrial motion control, and will invade on 802.15.4 mesh system wireless.

It needs two layers to get ip address. to use ipv6 for infinite number of nodes in a mesh. There is embedded single board computers to stack on ZigBee and work the many connectivity of many devices.

Linux will have to include wireless 802.15.4?
