Chapter · Zigbee
Security, hubs and the bench
Security depends on setup, Zigbee against Thread and Matter, what happens when it fails, and the ESP32 bench.
- 10Security depends on setup5 minZigbee has the cryptographic mechanisms, and what you get depends on how a device was added. This lesson compares a legacy onboarding with an install-code onboarding and turns a replayed frame away.
- 11Zigbee, Thread, Matter and hubs5 minZigbee, Thread and Matter are three different things that sometimes share a radio or a house. This lesson shows a coordinator dongle, a host and a bridge, and what crosses the boundary.
- 12What happens when it fails?5 minWhen a Zigbee device goes quiet, the failed operation and its evidence point to the cause, and distance or signal strength alone does not. This lesson reads four faults off five readings.
- 13On the ESP32 bench5 minOf Espressif's chips, the H2, C6 and C5 have the 802.15.4 radio that Zigbee needs. This lesson chooses a role, starts a network and shows the report it makes, then hands over to the ESP32 chapter for the code.
Start at 10 and read down — the order is the order things get easier in. Or take the one with your part in it; every article stands on its own, and links back to whatever it needs.
