Medical IoT Gateway | Polyglot Engineer Portfolio

Medical IoT Gateway is an ESP32-based gateway device that acts as a universal communication bridge between medical devices and a centralized monitoring platform. By speaking each device's native protocol and normalizing everything into MQTT, it streams health data to a real-time dashboard — unifying 15+ medical devices into a single digital health system.

Medical IoT Gateway Device View

Overview

Hospitals and clinics often run a mix of medical devices that each speak a different communication protocol, leaving valuable examination data stranded on isolated machines. The Medical IoT Gateway solves this by sitting between the devices and the cloud: it collects health data over BLE, TCP/IP, and USB simultaneously, processes it through a reliable RTOS-based firmware pipeline, and publishes it to an MQTT network for real-time visualization on a monitoring dashboard.

Tech Stack

Microcontroller: ESP32
Framework: ESP-IDF
Language: C++
RTOS: Real-time operating system for firmware reliability
Protocols In: BLE, TCP/IP, USB (simultaneous)
Protocol Out: MQTT (encrypted, real-time)
Pipeline: Real-time data pipeline to monitoring dashboard

Key Features

Multi-Protocol Ingestion: Communicates with medical devices over BLE, TCP/IP, and USB at the same time — no single-protocol limitation.
Protocol Reverse Engineering: Firmware built on reverse-engineered medical device communication protocols to unlock data from closed devices.
MQTT Bridge: Normalizes heterogeneous device data into encrypted MQTT messages for real-time delivery.
RTOS Reliability: Runs on a real-time operating system, keeping the gateway stable for continuous 24/7 operation.
Real-Time Data Pipeline: Purpose-built pipeline streams medical data to the dashboard monitoring platform with minimal latency.
Proven at Scale: Successfully integrated 15+ medical devices into one platform, simplifying healthcare data digitalization and integration in a single system.
End-to-End Data Flow: Medical Device → IoT Gateway → Publish MQTT → Dashboard Monitoring.
