IoT and M2M Framework for Secure Device Communication

Real Time Logic's IoT/M2M framework helps embedded products maintain secure, responsive communication between devices, gateways, browser dashboards, and backend application servers. Use it when small devices need live control, event updates, and encrypted connections without forcing every product through a heavyweight cloud stack.

Use the IoT/M2M Framework When

  • Your devices need persistent, real-time communication with a server or browser UI.
  • You need secure M2M communication for microcontrollers, gateways, or industrial devices.
  • You want to choose between SMQ, WebSockets, MQTT, HTTPS, or a small custom TLS channel.
  • You need an application server foundation for dashboards, portals, and device coordination.

From M2M to Practical IoT

Machine-to-machine communication is simply one device exchanging data with another system. In real products, the system usually also needs human-facing dashboards, alarms, configuration pages, service access, secure authentication, and operational workflows. Real Time Logic's framework combines small embedded clients with application-server technology so device events can become useful information and remote actions can be delivered safely.

Small Device Clients

Use PikeHTTP, SharkSSL, WebSocket, SMQ, or compact custom TLS channels depending on memory and protocol needs.

Real-Time Dashboards

Keep browser interfaces synchronized with devices using persistent connections rather than polling-heavy designs.

Secure Transport

Use SharkSSL and certificate-based trust where device-to-server communication must be encrypted and authenticated.

Application Server Backend

Use Barracuda App Server, Mako Server, or Xedge to host portals, APIs, device logic, and protocol bridges.

Persistent Communication for Live Device Control

For many IoT products, the important requirement is not just sending data to a server; it is keeping devices, operators, and web applications synchronized. Persistent connections make event notification immediate in both directions and avoid the latency and overhead of frequent polling.

Depending on the product, this can be implemented with SMQ, WebSockets, MQTT, or a compact TLS channel built directly on SharkSSL. Very small devices can use a minimal client, while gateways and application servers can host richer logic, dashboards, and device management workflows.

Choosing the Right Communication Layer

  • Use SMQ for browser-to-device messaging, private IoT portals, and simple publish/subscribe applications.
  • Use WebSockets when the application needs a standard full-duplex browser protocol.
  • Use MQTT when your product must integrate with existing MQTT infrastructure or Sparkplug systems.
  • Use PikeHTTP for compact HTTPS client workflows such as REST calls, uploads, and periodic status reports.
  • Use SharkSSL directly when the device needs the smallest secure custom channel and you control both ends.

For newer product designs, start with the SMQ protocol overview, the embedded WebSocket libraries, or the Intelligent Edge Controller page depending on whether the project is device messaging, browser integration, or a programmable industrial gateway.
