Bluetooth Mesh and Zephyr

on YouTube ↗46m

" summary

Bluetooth Mesh (spec 2017) uses Bluetooth Low Energy and supports networks up to 32,000 nodes with up to 127 hops and about 200 certified products; Zephyr RTOS runs mesh on low-cost hardware (BBC micro:bit and ~200 boards). The implementation uses models like generic on/off and HSL, a publish/subscribe addressing scheme, provisioning with network/app keys, relays/friend/proxy roles, and probabilistic retransmit for reliability. A 16-node Zephyr demo (Web Bluetooth proxy + browser UI) is implemented and the live demo works.
