Power ETH_PHY_POWER down for 200 ms and back up 200 ms before ETH.begin() so the PHY always gets a true cold start. A warm PHY left in a stale state (reproduced on Theengs Bridge v1.1 with PSRAM enabled after an NVS erase) can flap the link until a manual power cycle: it reports up for one poll, then down for several seconds, forever, so DHCP never completes. The short reset the Ethernet driver performs on its own does not clear that state; a power cycle with a settle window before begin() does. On a hardware-in-the- loop bench the same provocation went from flapping every trial to flapping in none of them (4/4). Enabled via -DETH_PHY_COLD_CYCLE, only active when ETH_PHY_POWER is a valid pin, at the cost of ~400 ms added boot time. Set by default on both Theengs Bridge environments.

OpenMQTTGateway aims to unify various technologies and protocols into a single firmware. This reduces the need for multiple physical bridges and streamlines diverse technologies under the widely-used MQTT protocol.
