Bluetooth Mesh and Zephyr

on YouTube ↗46m

" summary

Explains Bluetooth Mesh fundamentals and real Zephyr firmware work: networking roles relay, friend, proxy; multicast group addressing and publish/subscribe; support for up to 127 hops and logical limit of 32,767 nodes. Shows Zephyr model APIs, opcodes, buffers and send/receive code, AES‑CCM encryption, provisioning and per-device/application keys. Demo stitches 67 BBC micro:bit nodes into groups controlled via a Web Bluetooth proxy; demo mostly works but required resets and tuning, and Zephyr sample code is ready to build on.
