About MQTT
MQTT (Message Queuing Telemetry Transport) is a lightweight publish-subscribe messaging protocol designed for resource-constrained devices and low-bandwidth, high-latency networks. Originally created by IBM for satellite link telemetry, MQTT has become the de facto standard for IoT communication — used by everything from smart home devices to industrial control systems.
At Codyviaa, MQTT is the communication backbone of our IoT solutions. Its publish-subscribe model decouples device firmware from cloud backend logic, meaning we can update server-side processing without touching device code. The protocol's minimal overhead — a MQTT CONNECT packet is just 2 bytes — makes it ideal for battery-powered sensors that need to transmit data over cellular or LoRa networks.
We implement MQTT with quality-of-service (QoS) levels tailored to each use case: QoS 0 for high-frequency sensor telemetry where occasional message loss is acceptable, and QoS 1 or 2 for critical commands like device configuration changes or emergency alerts. Our NestJS backends subscribe to MQTT topics via AWS IoT Core, processing incoming data in real time and persisting it to PostgreSQL for historical analysis.
What We Build With MQTT
Real-world applications and use cases where MQTT delivers measurable results.
Real-time telemetry from IoT sensors and edge devices
Command and control messaging for remote device management
Live location tracking for fleet and asset management
Smart home automation with low-latency device communication
Industrial monitoring with guaranteed message delivery
Why Codyviaa Uses MQTT
Every technology in our stack earns its place. Here's why MQTT is a core part of how we build.
Minimal protocol overhead (as low as 2 bytes per message header) makes MQTT ideal for battery-powered and bandwidth-constrained IoT devices our clients deploy in the field.
The publish-subscribe model cleanly decouples devices from backend services, letting us evolve server-side logic independently of firmware — reducing deployment risk.
Configurable QoS levels let us balance reliability against bandwidth for each message type — fire-and-forget for telemetry, guaranteed delivery for critical commands.
Native support in AWS IoT Core and NestJS means MQTT integrates seamlessly into our existing infrastructure without additional middleware or protocol bridges.
