Overview
Choose communication protocols around power, bandwidth and device constraints.
Design considerations
Constrained devices make trade-offs between range, energy, latency and throughput. Compare link technologies against the deployment environment. Application protocols such as MQTT and CoAP serve different delivery and communication patterns.
Operational practice
Plan addressing, gateways and secure device onboarding. Encryption, access control, updates and message handling should be considered together. Validate behaviour during packet loss and disconnection.
