Using OpenThread to Enable Low-Power IP Connectivity on Your MCU Project
summary
OpenThread brings IPv6 mesh to coin‑cell devices by combining 802.15.4 radios, 6LoWPAN, header compression and sleep‑aware parents so a device sending ~36‑byte reports every 60 s and polling its parent every 4 s can target a 200 mAh coin cell for ~3 years. The stack runs on Zephyr or bare metal, supports RCP/NCP and OTBR, and adds mDNS discovery proxy plus Service Registration Protocol to avoid multicast. A transparent gateway (Raspberry Pi 4 + Nordic USB dongle + Zephyr nodes) is implemented, upstreamed and demoed working.
