ESP32-MDB Library Compatibility and MQTT Integration Query

[hassan7khanani]

I am evaluating the esp32-mdb codebase for a project and have two primary questions:

Compatibility: Does the esp32-mdb library fully support the MDB Standard v4.3?

Architecture: I plan to implement a system where the ESP32 acts as an MDB slave to:

Poll the vending machine for its status and inventory levels.

Publish this data via MQTT to a broker.

Subscribe to an MQTT topic to receive commands, which it will then translate into MDB commands to initiate a product vend.

Can the library facilitate this bidirectional MDB/MQTT bridge functionality?
