a live-stack sweep of all 36 drivers surfaced five sdk-level defects that left reads dead or the whole fleet unbootable: - drop the empty spring.main stub in the shared driver profile; the boot 4.1 binder rejects null-valued keys and every driver died at startup with a bind exception - rename the schedule enable flag to enable to match what every driver application.yml actually spells; with the old enabled key the read and custom quartz jobs were silently never scheduled - treat proto3 zero-versions as unset when reconciling registration so a driver restart re-registers instead of failing the optimistic lock with 'driver version conflict' - ignore the driver's own registration event that can be consumed before applymetadata finishes instead of logging an error - initialize jdbc/serial connection maps eagerly: the registration event handler invalidates pools and nped on a lazy-null map - ble: exclude the guava 18 pin dragged in by bluetooth-manager - kafka: use the starter (boot 4 split autoconfigurations out of the bare jar) and read the compose-provided bootstrap variable - lwm2m: pin californium to the 3.x api leshan m14 needs and configure an explicit coap endpoint - mqtt: replace the orphaned spring-integration gateway with a paho publisher so the send path exists again - boot sweep result: 36/36 drivers start, 0 errors
DC3 Driver Mitsubishi Melsec
Overview
dc3-driver-melsec is the Mitsubishi Melsec MC protocol driver of the IoT DC3 platform. It connects to Melsec PLCs over
the MC protocol using the iot-communication library, reading and writing device memory addresses (e.g. D100, M0,
X10, W200) by point value type.

The module application.yml is authoritative for attribute codes, types, default values, scheduling, health, and local
buffering. Keep this README aligned when those user-facing settings change.
Prerequisites
A reachable Mitsubishi Melsec PLC (or simulator) exposing the MC protocol over TCP, addressable by the configured host and port.
